I like the core mechanics a lot! This one has a potential to become good game in it's own right outside the compo.

There are two problems:
1. lack of the final game goal (what defines the game end)
This could be fixed by stating goal at the beginning or giving some clues inside the game.
2. monotony
This could be fixed by adding more variety to the evolution of the player and enemies. Some control on how the evolution goes could be good too. This way player can set goals for herself

Also kudos for web version!

As @Nek said, it has potential to get extremely awesome with more work! Liking it! Also, WebPlayer FTW!

I'm probably going to make a more polished-jam version today, needs a bunch more programmer art, world&dungeon decoration-items and different enemies.

Enhanced Jam Version (72h) is also available now :

Various different enemy types, also roaming the surface world. Epic boss battle at the End. (sort of)
Deco, dungeon walls, themed dungeon coloring and lots of tweaking.

Regarding control on how evolution goes : that is possible to a degree, every dungeon has one red gene, but also possibly multiple genes, so when exploring every dungeon fully leads to a more defensive character, whereas just rushing to the red and then going to the next is more agressive but also more dangerous later.

I love the look on the avatar's face.

Enjoyed this game a lot, but became a bit too repetitive early. I especially liked the suprised-looking face of the character I started with! After evolving he became angry, but later suprised again, good times :P

Excellent submission! Surprisingly addictive -- though you run out of content relatively fast. Would love to see it pursued further!

I didn't understand all the mechanics, but overall it was pretty fun :-)

I really liked the song!

Nice concept. But it gets somewhat repetitive. Great game overall!

This was fun. I usually hate mouse-based movement control schemes, but this one I actually liked!

The basic game idea does seem indeed very good and worth carrying on.

I found the combat outcomes a bit random depending on who got a hit in first. I don't think I ever found any blue genes.

I liked that the game felt like it started immediately, purely because of the mouse controls :)
