Amazing game.
for 5$ iv spent more hours playing the game than a modern day FPS.
Feels very arcade, the game has a great difficulty curve, deaths don't feel like a punishment [rougelike, duh] and the random element does a great job at keeping the game enjoyable. Even after 30 roundsof the game i still find things i never came across in prevoius playthroughs, be it a secret room or item. The music is wonderful, and this demo helped push me over the edge to buy the full game. I was not disapointed.
To anyone still on the edge as to if they should buy the game or not, i strongly urge you to pick it up instead of order a pizza, or whatever it is you do with 5$, you will have a lot of fun.
