For those who come here for the answer: Press E to sacrifice. For the author: nice idea, good implementation of shooting and well-themed locations. The only problem I had is not very mobile IA. It would be fun if they tried to approach or hide instead of standing.

I like the graphics. Nice job!

pretty much became a angel of death, until i was taken out by a bomb. love it!

This looks really good! Shame I'm on a Mac I'd really love to try it!

@secretmapper I will try to make a Html5 version after this match if I can. Thanks for supporting me!

Those bombs... They just dash xD.. So good :D

Interesting concept, but the game lacks juice and feedback.

Overall is this fine top down shooter. The controls and the graphics is really good. But I would liked a bit less levels, and instead get some music/sound effects, and perhaps a bit better AI. But overall a very well made LD game. Well done.

Addicting game, I like the art. I think that speeding up movement is a bit too strong, because it makes sacrifices of the other upgrades less important. Also one bug is that bullets stay in the scene when the rooms change. Good job!

@shulgaboy Good advice! As you mention the enemy is stand and still, I make a quick bug fix. The bool value "Keep Firing" setting of the red enemy's "FireBehavior" was accidently been turn off during early test. Thank you for reminding me！

Really interesting concept where you need to use sacrifices wisely. I just wasn't sure what is the meaning of sacrificing your own health multiple times while you can only pick one upgrade.

Anyway, fun game!

@blodyavenger In early design idea, the player can choose not to sacrifice the blood to face the boss dierectly. Against the horde of enemy and a boss.

And the level keep generate with different type of enemy spawning. If player take less damage from enemy, the can save more health point for power up. When the player think he is strong enough, head to the boss battle. Kill the demon and the game go an end.
But random generation is hard to control, easily let a level become an impossible quest. Need a lot of time to change the parameters of the spawner.

So, I keep the hp sacrifices mechanism to connected with the story. And the level turn into a static one. (I make some meme of the old western movie).

Looks really good!

Nice title! Wish it had some audio, otherwise pretty fun, death animations are cool!

I liked the variety of enemies and the sacrificing mechanic. The game would feel so much better with some audio.

I won on my first try with a score of 430 and 2 health left - it would have been nice if one of the sacrifice options between levels was to get some health back (at the expense of something else obviously). By the end I was just dashing round the edge of the level firing big bursts of bullets that went everywhere - it was fun!

Good game! I died at 325 points, unfortunately. I liked the sacrifice idea, the graphics are great as well! As others have pointed out, some audio would have been great, but it's OK, 48h is a short span of time ^^

Otherwise, the handling is solid. Congrats!

Really good take on the theme, very well integrated into game mechanics, thats what I like to see in ludum dare games. Game was fun, art was alright. The big problem is no sound of course, even a bullet sound effect would have been ok. Good job especially on the theme.

Great game. Your project is very interesting with smooth movements and a good use of the theme. Minimalist aesthetic is cute. In technical terms I would like to know more about IA because it was skilled. Well done. However I would like to hear a background music track or some sounds when I walk or I shot. I assume that you could add them easily with more time. A great entry. Thank you ++

@geckoo1337 Thanks for your support! And about the AI I make a simple description. (ps. I am not a skillful English speaker so it would be some of gramma mistakes below, sry)

I made a simple AI system base on a programming patterns called "Finite state machines"(FSM). The idea of the FSM is that you got a group of state, and the character can only be one state at a time. At the same time, the state will check something(do them in the update function call each frame or check player's input) to transform to other state.

So enemy beavior is different but the state of the beavior is same. Idle for do nothing, Move for patrol, Shoot when they found the player(or hit the shoot trigger base on the AI setting)m Chase when they found the player.

Due to a lack of time for coding a FSM myself, simply use the animatior controller combine with the behavior of each animation statement can do a same effect a bit similiar to FSM. Make a bullet spawnsystem but set different parameter to change the each enemy shooting style. Make a bool value to set if they keep chase when they found player, and how long they will keep chasing. And so on.

You can download the source code to check it out, and you can leave a comment below if you got any further questions.

It's simple and beautiful. The gameplay remembers me alot of Nuklear Throne, liked it a lot!

Rate me back if you can :)

Cool little game) I really liked the graphics, for example, how enemies die and leave hats behind me) I always chose shooting speed and I had a couple of miniguns in my hands) Thanks for the cool project)

Hahah this is an awesome game. I love much you can mess with your stats and change the game. First time I went for spread, then I went for quickly firing bullets.

This game was pretty hurt by the lack of sound though. Next time, there are a bunch of sound effect generators you can use (sfxr is the main one I think of), I think just having some simple sound effects would make a big difference :)

Overall, really nice game!

Really nice game, it was really fun to play. I think however that it would be nicer if there is some way to regain health. I hardly got hit but die because of the sacrifice I need to make.

Lots of fun, and good use of theme! I enjoyed the sacrifice mechanic!

Nice game! Pretty cool idea and fun gameplay

The music or other sounds could make it better. But it really good to play. I like it :smile: Good luck!

Yay! I won! Congrats on the compo entry! I had fun playing it, even though sometimes I was getting a bit angry with the aiming (my fault, I sacrificed it for MORE BULLETS)

What I liked the most
- the idea of upgrades debilitating other attributes.
- levels were designed instead of being procedurally generated and it still offered a pretty good length for a game jam entry. Also, the way you were introducing new enemies on further levels.
- overall funny writing.

Biggest problems for me
- projectiles too small! Shooting peas becomes a bit frustrating quite quickly, specially at the beginning when they are so slow (the speed can be increased though, but not the size).
- the movement could use a bit smoothing.

Overall, it's a really good entry!

Cheers
