hey, thanks for trying out my game!
Restarting on a level is not a bad idea. The concept of the game was supposed to be kind of a rogue lite though, so it might affect it from that point of view. However I know spelunky has a concept like that where you can skip sections at the cost of actual game progression. There is a player unlockable in escape the ether that allows the player to start at level 50 when you achieve this level normally in game, but you can't gain points while playing as it. maybe I could increase this mechanic a bit and get the best of both worlds?
Yes I agree with your comments about the end scene. I definitely need to improve this somehow, I'll have a think about it.
