Several frustrating aspects of gameplay that could be improved. For one, wasting matches when not in front of an enemy or chest is very aggravating. Second, you never really get to feel OP or powerful. I was hoping I'd get to run through the second time with all my upgrades, against the beginning low-level challenge, but no. Couldn't even complete one run the 2nd time, too hard. Finally, I wish I could undo some up the upgrades (toggle off) like the one that allows matches at the start of th run (they get wasted). I don't like the "You Win" participation trophy, we're not all Millenials. Had I known all of this, I wouldn't have bought the game.
