Really cool idea, I liked it a lot! Very clever how you integrated (and reversed) the mechanic of choosing new items and upgrades at the end of every round. The artstyle is great in that it's minimalistic but clear, and the music goes well. I would have appreciated something to show where the hero's destination was - for example, a red line - and it seemed a little too easy, given that I defeated the hero in the third round. It would also help if there was an explanation about what each of the monsters do. Other than that, good game! Well done!
