This game got frustrating in the best way possible. It just made me want to keep trying, especially around stage 13 or 14. I eventually gave up due to time constraints but this is an awesome game.
It feels like the kind of game that really wants to show the player all the places they've died.
I think the game might benefit from just the smallest transition time between death and the next attempt. Even just 1/4 of a second or less. As-is, it's just so small (maybe nonexistent?) that it feels more like being teleported than being respawned.
Super, super, super great game!
