TENET SECONDS by MoebiusMeow

A mind-blowing puzzle game of time. Inspired by the movie TENET.

Have you ever thought about reverting the direction of time?
The direction of time changes every 10 seconds. When the end of 10 seconds is reached, the time flows from the 10th second to 1st second.
All physic objects have their own direction of time. More precisely, Orange indicates that the time of the object is normal, while blue indicates that the time of the object is inversed.
*The objects move forward when their direction of time is the same with the world. *
*Otherwise, the objects move backward (rewind) *, which means that they are heading back to their former positions.

Guide for newcomer of time travelling
- You'll need to collect all the orbs in each level.
You can collect orbs with anything hitting them, there is no need to touch them with your charactor.
Press A, D to move around, space to jump.
Holding W while standing on the time machine, you can change your direction of time when the next 10 seconds comes.
Press R to restart, Esc to exit.
Have trouble solving the puzzle? Drawing a timeline on a paper may help.

For time travel experts
When you activate the time machine, don't look back. The last 10 seconds that you have been experienced are lost forever. But you'll have another 10 seconds lifetime in the reversed timeline.
The rewind procedure is absolute, which means that even the heaviest things can't stop the rewinding objects.

Skipping levels
- You are free to challenge the next 3 unfinished levels, which means that you can go to the next level if you cannot solve some puzzle,
Unintended solution?
- There are indeed different solutions other than the designed solution. I even figured out myself when testing the levels.
- I decided to keep them possible after all. Feel frese to use trick to solve the puzzle!

Thanks!
I have to admit that the introduction of the mechanics is not clear enought considering the complexity. It is hard to convey that both "standing on the machine" and "reaching 10 second" have to be satisfied.
It was intended that players can learn to use 'W' in level 2.
At first I dont understand the meaning of "W" as sell. The mecanics are unexpected and interesting, good job!
Thanks! I'm glad that you like the game.
Actually, there is no need to use time reversing in level 8 since it is designed to introduce the trick of multiple characters, which is crucial in level 9. (stack two characters and jump)
Indeed some levels are really hard to figure out (such as level 7). That's why players are allowed to skip them and challenge the next levels. However when you solve the challenging puzzles you might feel like being the master of time XD
I have uploaded a walkthrough video in comments. You can check it out if you want to know the designed solution of each level. (By the way there are also many different solutions other than those in the video)
super smooth controls, very beautiful visuals, and the little gun was fun too haha. Great entry!
@bosce I'm glad you like it. By the way it was once intended to make some puzzles with the gun and bullets in the reversed time at first. I even made reversed sound effects for the gun. However I could not finish the gun system on time. Then I removed the puzzles but the little gun was kept. XD
I am not sure how I feel about the physics system. It DOES make for some cool puzzles, but it also makes execution pretty difficult, even once you know the answer. Even so, these are nitpicks against a top-tier entry. Well done.
Graphics are very cool!
Unexpededly clever with a whooping 10 levels!
(For that matter I felt the blue objects were somewhat inconsistent with the game's own rules: at the start of the level they are static for 10 seconds, but for every other cycle from then on, they will spend those 10 seconds reversing through their motions.)
It's nice that you note in the description that there are unintended solutions, but I think I solved more levels unintentionally than intentionally :D That also makes me wonder if there isn't too much freedom in the system vs constraints in the level design.
I think I would have spent more time trying to solve the remaining levels had it not been for the platforming: it was way too floaty and jumping from the diagonal platforms was a very bad experience.
The visuals and audio were quite polished. Playing music like this in reverse is always an interesting sound, and it didn't get old too quickly.
Thanks for your detailed feedback! I tried to introduce the mechanics using the first few levels, though I have to admit that it was not clear enough. As a result, placing a time machine in the first level is not really a good attempt.
It was intended for players to try the machine themselves and obtain a brief understanding of the machine. During their exploration in level 1, they would probably meet the time reversion in 10 seconds. And then there would be a test for these basic mechanics in level 2. I thought that players can feel like they're clever when they figure out all these things by themselves. However, the fact is that I should have made it clear,
This also holds for the orb collecting mechanics. In level 4 there is a ball naturally running towards then orb which is on the top platform. Then player have to push another ball to collect orbs. I tried to use this level to tell players that you can use anything to collect orbs. (When it comes to orbs with blue objects, I originally designed different colors of orbs but I didn't make it to implement due to a lack of time.)
Indeed the freezed blue objects are a little strange considering the whole mechanics. As far as I know, you can use this feature to push the big blue box in level 7. (It was actually my first solution to this level.) The point is that even though the time is limited to 0-10 second, objects do not always go in loops, since the unseen former loop is undetermined. I also planned to further exploring this mechanics if there was more time.
By the way in level 6 you can directly jump to the orb if you push the top part of the box and perform a jump on it. The moment feeling that "Oh I'm more clever than the designer!" is great. So didn't lock the rotation of the box as in level 7.
Indeed the physic system need to be optimized. I should have done it better.
After all, thanks for your advice! ^^
I liked simplicity of the graphics. The mechanics weren't exactly easy to get in to - but I did like the core concept. Really really nice entry.
If I could pick a negative to feedback on; it seems like you could implement more audio with non-linearity versus the current offering, which I still enjoyed and found easy on the ears but so much I would just love to hear more of it ha :)
Thank you for letting me play it, highly recommended to anyone who hasn't yet!
Also the art style are amazing! I love the lighting and how the shadows of the clocks move as time goes by (or goes back).
The controls felt awkward sometimes. I don't play many platformer games and I can't put my finger on it, but the platforming did not go as I want it to be in level 8 and the bottom right part of level 9.
