Well the game is playable, but only one class, the Knight, is really usable, because the Mage's magic is not very powerfull and the unicorn takes a lot of damage when it attacks.

Also consider rounding up the health, long decimal numbers aren't very pretty to look at and don't fit in the health bar.

The music is a bit repetitive too, but I can't blame that seeing it's a compo entry.

With more work put into it, it can really become a full fledge arena survival. Please don't get discourage by my feedback though, I know how hard it is to create a game from scratch in so little time and by improving it afterwards, it can make for a great game.

As the last guy said, rounding your numbers would help. However I found the unicorn very playable, considering I could infinitely dash around with spacebar. Also, Going up or left does not work with WASD, you may want to look at that. But overall, good concept. edit: didn't read controls, my bad. I guess ZQSD works for me.

Fun little game.
I tried the mage, and felt like he was super powerful in later levels, since his attack hits everything inside the circle. Got to level 22 before I died.
I think there might be a memory leak in the game, because when I died, my computer completely froze. (It's a newer computer, nothing else was running, and it hasn't frozen before)

What a demonic laughter :-D

Fun, toughh game, nice that you could implement 3 characters.
For myself, unicorn was the hardest, knight the "easiest". Took some time till I figuerd out that I had to hit the medipacs itself to take them.

Nice Game!

Nice game! I like that you have to use different strategy for each character. The unicorn game mechanics seems to require more elaboration

I'm not sure I understood everything but in any case, nice work compared to your first participation. The implementation of different character holes allows us to place in three distinct bie cases. A good game base. Keep going!
