Very cool graphics! Idea is decent, could be turned into something bigger. You need more difficulty, right now you can place traps in all the rooms and be able to defeat the hero before you run out of mana or whatever the blue thing is. 

Absolutely stunning game. 

Neat game, simple to play but really entertaining. Although it is a bit too easy to kill the hero after the acid. I can see this game being expanded into a complex card puzzle game. Great work!

I liked the idea and concept,
this idea can become great strategy game.
well done!

I can see that a lot of work went into the graphics, as for the gameplay I think that with more work it could be fun. Some ideas: remove the timer, make it turn based, make the trap animation faster, add more variables so there is an incentive to use more traps, maybe limit the amount of traps that can be placed.

This game looks awesome!

The idea is good and it's fun to play.
