nice, i wish the upgrades stacked or there was some sort of progression, I played until I got 1000 score so I don't know if the game changed in some way. the jump and specially the double jump didnt feel too good since I couldnt control when i'd fall so sometimes id just land on a pit or crystal. could be cool if you also gained score for taking risks like jumping over obstacles. hope im not too critical since its a jam game, but this is very polished and already pretty fun.
