Thanks for playing! I'm glad you liked my goofy writing lol. Yeah originally the reroll was just a debug command for me only, but the game felt so rng I left it in as a sort of band-aid fix, which then pulled it around and made rerolling until you found the specific piece you wanted the easiest way to play. There are definitely better solutions there to limit rerolling or make it more interesting/less required.
Looking at it now, yeah there's pretty much no reason why the player shouldn't be able to just restart from the level their on. Especially for a game jam game. One of those thoughtless things you don't really think about until after someone points it out to you lol.
Again, thanks for playing!
