Pretty damn funny, animations are awesome, sound balance is a little off balance here and there but damn this was pretty fun!

Hi there, nice work. I like the basic idea, reminded me of the old natural selection (hl1 mod).

Unfortunately I cannot get past level1 since there is an error occurring:

Really like the idea! Would love to see a post-compo of this. For now, the bug ^ won't let me get that far :( And there probably should be multiple spots where enemies come from, because I'm spawnkilling them like crazy atm.
And the animation are awesome!!! :o

Have an error:

Looking good. Animations are delicious =)

Not sure what's crashing the game, at first it was after I spammed the Tab key, then I was spamming the quills attack when the 3rd wave was announced. Shame because I was having a lot of fun. I'd like to see more of this.
Remember, the rules allow you to fix game breaking bugs.

Cool ideas, but a little buggy:
- I couldn't see the blocks, only the background, for several minutes. Then I switched to a worker, dug, and bam the blocks started showing.
- I got a crash at the beginning of wave 3.
- Got stuck in flying mod, with the flying sound, for trying to climb a narrow vertical shaft. Had to fall back down for it to stop.

But it's a nice concept and could be fun once debugged.

Great stuff! very nice job! love the game play and graphics!

The game it's pretty nice, it was a bit hard to hit the soldiers but anyway was fun, the sounds are a bit bugged too, overlaping. I have the same error than SaintHeiser when wave 2 starts.
