Great art, great concept, fun music (even if at least some of it is definitely borrowed)
This would really work as an actual full title!
For the downsides: After a while of playing, no adventurers spawned in anymore so I was unable to progress. Also, the battle-music cuts out after you have killed your first adventurer per wave. And this game could really benefit from you being able to sell the monsters too, instead of just the equipments. Also this game doesn't really have a difficulty-curve
