Very smooth gameplay

Awesome!

I kinda like the different "specimens" but I really don't see how the new specimens are selected. Is it done statistically, or programmatically, or what?

Otherwise the background was rather bland. Gameplay was pretty basic.

Simple and effective, and I love how smooth the whole is!

The two things I didn't like : The BG texture (I don't get it x) ) and I didn't really see any difference between the enemies

There's a few things that goes to picking the specimen. Primarily it's how much damage each creature dealt to the player. Secondary is how many bullets it fired, and then tertiary would be how long it lived and how close it walked to the player.

The background is a photo of a wall, btw. I didn't really have good thematic ideas for the game. :P

This came out really well.

It isn't the first time the walls of CB2 have made their way into a game :).

The 4 way movement + 4 way shooting makes for some frantic gameplay. It's pretty fun! I lasted 3 rounds and killed 54 enemies. The music is pretty great too

My game is quite similiar to yours :) Gameplay is smooth and fun, but gets a bit repetetiv after a while. I really dig the music :)

Fantastic! 60fps. Love the health bars. I wish you could hold down two arrow keys for diagonal shots. Reminds me of robotron, smash tv etc. Keep up the awesome work.

Solid twin-stick shooter! I like the bullet-speed, it's fast enough to feel badass, but slow enough for enemies to slip through.

Music works surprisingly well. It's catchy.

The game did tend to choke a bit, and I feel the evoltuion-aspect of the enemies is too... "mild". You don't really notice unless you look for it (at least in the first handful of rounds)

Very smooth, feels great to play, fun. :)

Really nice game, enjoyed it quite a lot. A few of the evolutions were REALLY weird, though ;)

Very simple and fun to play, but maybe too simple. I think the evolution of the enemies wasn't too important or explicit, it could be better explained what was happening on this matter. As far as I could tell, there wasn't much I could do regarding the evolution mechanic to plan a strategy or something like that :P
At first I thought it was too easy, but the difficulty curve is rather steep and it gets terribly hard to avoid bullets! I believe the shots are in random directions, so when it gets full of bullets there isn't a pattern or anything I can use to predict how to avoid them...
In any case, I survived 12 rounds and killed 188 enemies. :D
Nice little game although I think it requires more work to make the evolutions meaningful for the gameplay.

I sat in the top left corner shooting right & got to level 10. Enjoyed the proc creatures.

Well, Jack, it's a 48h game, so there may be some slip ups like that. :P Also, I think a good player can get further still with "real" play, so I don't think it's a big problem.

LegacyCrono, I do agree that the evolution could be more meaningful. I may work on a new version post-compo and try to figure out ways to make the evolution aspect more interesting. I do think there's real potential there.

Cute twin shooter! Somehow some creatures evolved to having only one eye ... o_O

Good shooting game with evolving enemies :)

Not bad, racy music, managed 5 waves.

It was okay. Very, very basic and simple though, there was really nothing new and it got a bit dull fast.

The fighting is fun and the evolution system work great. I missed the diagonal shots. You could easily improve graphics by adding some soft shade to your spheres, but I'm not sure you can access flash design tools and gradients are painful to use with code. If you don't have flash IDE you can still improve gfx by adding particles on monster death instead of the shrink effect. Pop and explosions tend to be more rewarding than a vanish/shrinking effect...
Nice music :)

The tune was very catchy. :) It felt a bit annoying that you couldn't shoot diagonally, I found myself missing the feature quite a lot. It was quite hard to keep track of the evolution/mutation/gene process, were the alpha specimens for each round chosen by random? All in all, the game was fun to play, but could've been even more fun with for example mouse aim.

A very simple shooter but it works well. You say there is some kind of genetic algorithm at work but honestly I couldn't tell the difference from random generation. The audio was a bit repetitive... Also I like the wall texture :)
