Nice first entry. I found it funny bullets are moving fluently, but characters are moving in tiles. I first didn't realize, but it makes perfect sense to do so from coding pov. gj

Thank you :D I did it tile movement because I didnt really have time to try to get it to be fluid :D

Getting just a black window on OS/X

Got stuck and then fell of the level. Hey don't get me wrong I liked it but you should keep at this one.

Hey liked it and you should keep at this one.

Glamdring, anychance you could run it from the terminal and comment with the error you get please? I dont have a mac so I cant test myself :) Thank you

I liked this game because it's like one of the old platformers that you would get on a website in Flash, but it has the nice evolution twist which rewards the player as they continue to play.

The game stays 1s and then quit (WinXp sp3)

Did you extract it from the zip?

Timster studios Thank you :)

Instructions are misleading! :) I couldn't get it to shoot with the spacebar. Clicking works though. Tile movement is weird. But the high jumping and gliding makes it fun.

Hey JPatrick, I ran into some trouble getting your game running. I'm testing this with a Windows 7 32-bit box. Here's some data:

Interesting game! I made it to level 8.

A few notes:
-I couldn't shoot with spacebar. After a while, I figured out I could click (left mouse button) to shoot.
-It seems like gravity is entirely single tile based which takes some getting used to. In particular, it seems like when you land on a tile, it takes about a second to be able to jump again.
-It took a bit to notice the enemies don't hurt the player, they shift they player by a tile space left or right.

Nifty things:
-The shooting portion is pretty fun. I like the speed you can fire.
-Graphics and sound effects are pretty nice.

Cool game! Good luck!

Good first attempt. I could not get the game to fire when pressing space-bar (is this a late mutation?)

I also found that sometimes enemies would bunch up on the edge of a platform and stay there, making it difficult, if not impossible to make it to that platform and making the level unwinnable.

Oh, sorry, shooting is left mouse, I was rushing to add the instructions at the end :) mottmat,your computer does not support opengl, so you wont be able to play, sorry

Cannot launch on my MBP :-(

can you run it from the terminal and post the error here?

I don´t like jumping very much... It is somehow wierd. I don´t know, maybe you fall too slow? And also mutations... I got like 10 of them but there wasn´t any change. (Maybe they will be useful at the end?)
But anyway, it is good game. I am definitely going to play it again. (And again, and again...)

Nice concept, but the movement was a bit annoying

Black screen in OSX

why is there no executable in the windows archive?

black screen on OSX here as well, ran it from terminal (java -jar mutate_osx.jar) got no errors at all.

Hmm, thank you for running it :) Looks like im gonna have to remove osx download :(

Unusual movement but I like it. Of course it could be better animated.
Some more information about the muations you get would be fine, too.
Good game so far.

Yeah, im not the best at graphics :D

Fun game it took a couple minutes to get used to the controls/speed of the game but i enjoyed it.

click to fire with the mouse without being able to aim is not the best. Maybe attack with CTRL or spacebar, I don't know.
btw, good work =)

It was fun, but the tile-based movement was jarring, and jumping was really awkward.

An okay game. One of my problems was I did not know what the mutations were actually doing, since they weren't labeled. Also, on my opinion, the direction of shooting should have depended on where the mouse is relative to the player instead of the last direction the player moved in. Finally, a small design tip: the animation of the player and zombies is choppy, while the bullets move smoothly; you should pick one style or the other, because they don't blend well.

The player physics were pretty strange, and it took me a while to realize I had to press space at the end of each level to continue. Do the mutations do anything? I couldn't tell... Good effort though!

This game was great. I was having really awesome flashbacks to grade school when my friends and I would make"video games" on construction paper with pens. we Always had some maze thing going on and you needed to get a gun and a key and kill badguys.

This really hit home for me. Thanks for this game.

I had problems first with win7 but I looked at the settings in security and unchecked some crap. Here is a screen shot of what was stopping windows 7 from "dealing with it"

Nice job completing your first LD48. Thought the bullets / gravity were a little slow. Also, after completing a few levels I think the "You have 0 mutations" popped up a bunch of times.

Pretty cool game, but I found the controls and movement very frustrating. I also didn't get any mutations after a few levels, which made me wonder if I'd ever get them. If you tweak the controls/movement, I think it's got some potential for really being fun :)

Kept playing until a key spawned on top of the door and made it impossible to get through. passing through messages seems a little flaky too. I like the idea of randomized upgrades, but the player starts out so capable compared to the challenges, they were nearly ignorable.

the character jumps way too fast in relation to how fast he falls.
Try not to spam debug output into console; it often decreases performance significantly ;)

Haha, silly moving, but funny.

I was confused the clicking wouldn't shoot in the direction of the mouse but rather your last movement direction - why use the mouse button then? :S

The only thing who move smoothly is bullets, everything else not.. That was very annoying. Btw, is a good start for the first work ever! Keep doing! :)
