I see what the game was going for and I especially liked the snail. The fact that nothing has collisions are strange, but its okay. However that the skeletons just "vanish" through the floor by themselves without being killed or if killed by the knife, thus never dropping any gold makes it rather hard to progress. The bow and staff seems to work correctly in killing them, but even then they will just randomly disappear. After the first wave, nothing spawns and as only a few skeletons will actually be killed to drop gold, one can't buy anything either. This makes it somewhat tough to judge how proper cycle of this would feel like. 

The aesthetics works and the sounds for the weapons have a good impact (though maybe not matching the dagger action :P). I just wish I could play it as intended.

I couldn't really figure out what to do after beating the first wave of enemie. Tried talking to the snail but nothing happened, and no new enemies came. Very cool art tho!
