Wall jump was very fun and punching the enemies in the end made me laugh everytime. The dimension part of the platformer was cool as well. I think this kind of game would be for sure something what speedrunners would love to play, with more levels and mroe difficulty. It was fun to find different ways of beating the level (walljump at the correct time with dimension change, made you jump far :D)
Although I couldn't get past the ladder level, since once I pressed UP I couldn't do anything anymore, which was weird. At the end of the ladder I could jump again but just couldn't make it. Once I restarted there as well, it took me all the way to the start (maybe I lost enough lives or something that I didn't realise)
