Very nice! I did find it confuzing to control, I do see the light, but two buttons "Fast" and "Slow" would have been a bit easier to control. That being said, great game, good idea!

First play i got killed and the game freezed. Second time i killed the enemy but I had to wait before i was down. Idea is good tho'

Simple game and well done.

@jerre: Sorry for the freeze, thanks for mentioning.

@Faust: thanks~

Poor space invader aliens :( Now I truly know how they gotta feel. However, I was having some trouble shooting and moving at the same time (either I use my attention on incoming shots, I aim, or I just spam bullets and get killed). Nice game! :D

Fun little game. played it on my android np.
It was quite hard to get past the levels with 3+ spaceships though.

Thanks for playing.

@AyCe: You can't shoot while pressing any button because I use switch() on key listener (you use java too so you know) :D

@BarrensZeppelin: Yeah, but I managed to pass it by fully upgraded acceleration and base speed :)

I always use 2 boolean[], and when a key gets pressed, I use switch(keycode) in a function, which "converts" keycode to actual key index in the boolean[]'s. now i look if boolean[] no. 2 is true at that pos, if not, set both arrays to true on that index. in the key up, i again get the key index by the keycode and set both boolean[] at that index to false.

Why that? Well, if you want to use "hold", just look of boolean[] no. 1 is true at that index, if you want to use "click (and ignore if key stays pressed)" return the index of boolean[] no. 1 and set it to false.

Well just look at this: http://pastebin.com/raw.php?i=wf9A4jfe

Of course you are free to code as you want ^^

I played the Android version on my Galaxy S3. The blue gradient in the background does not fill the whole screen. The aliens only shoot if I touch within the blue gradient block.

The first few times I played I did not realize that I could make the invaders move faster by tilting the phone.

A great concept, inverting the roles of the space ship and aliens. Also quite difficult! :-)

@AyCe: Yeah I already know about that. I did this to prevent more shoot spamming (intended). Thanks btw! :)

@voidstar69: Thanks for trying. Yeah sorry about that. Within limited time I couldn't set up scaling, so max supported resolution is 800x480 which is my own phone Desire V :)

Nice clean style.

@fishbrain: thanks! yours is good too :)

Wow, I didn't expect that this particular take on an old classic would be so much fun, but it is! I sort of wish you had an occasional UFO helper fly by like in the original, but other than that it's solid!

@recursive frog: thanks for playing! I will remember to add UFO on post-compo version.

Nice little game. On my xperia s it seems that the background is not lined up and i have white space on top and right.

@dray: thanks for playing! yeah I made it fix on resolution. Xperia has about 850 x 480, 50px more than 800x480.

I like how the aliens open their mouth when dropping bombs. More people had the same idea, but I didn't so I think its a good idea.
The background was not right though and after destroying the hero, nothing happened. A bug maybe
?

@goerp: thanks for playing! it's not bug, I just forgot to add that win condition :)

I thought it would be hard to make a game around that mechanic, but you did a great job. As someone mentioned before I had some trouble with the speed up/down controls, and had to wait until I reached the bottom before proceeding, but the general game is well executed and great potential with further polish! =D

@Tommislav: Thanks for playing! yes Im planning for do the completed version, after new year maybe :)

Nice concept, but with some problems:

- If I hold the left arrow key to quicken the movement and then I reach the left border, I think it would be better, if it slows me down while keeping the left arrow key down, instead of resetting it.
- The enemie shots are too strong or too fast. Perhaps adding health to every alien? It is hard to have more than 1 or 2 aliens left.
- The game should change to the upgrade screen after I destroyed the last ship instead of waiting until I reached the bottom screen border.

@Jeremlas: Thanks for the feedback! :D

Hey, Drabiter, couldn't get this to work on my Mac. I'm saving it to play on my Windows machine before the end of voting!

@azurenimbus: thanks!

Hahaa! This is good! I love the angry faces it's a nice touch. Only 2 things: they should speed up when all the ships are gone and it's bad that the game quits when all aliens dead. Well I don't know if the latter is because of the Android structure - I just recently started learning it. :P

Anyway, love the idea, simple and clean implementation. Thanks!
