I loved this game. I think I played it til the end? Or at least *a* end? Spoilers below!
(Had fun regardless, but in case you want the info) I think I hit a glitch - got the 'Legendary???' card, and without trying to spoil too much, a certain something disappeared with maybe 1 hp left or so but the hp bar stayed on screen but I could still bubble around and be my bubbly self, it just seemed to break the game a bit. Left another mysterious item on screen with a lot of random letters as well. The legendary thing in question hit me right before it disappeared, but I also had shot it at the same time, maybe that caused something. Either way, really well done, I had a lot of fun rolling through it and the upgrades were awesome, absolutely fantastic entry!
