Nice time-pressure platformer with a good challenge. I like the different costume options, though it would be interesting if there were some gameplay elements tied to playing as Batman vs playing as Spiderman or others.
It's a little odd and counter-intuitive that I need to walk left to trigger the bully so that I can get onto the rest of the game so it feels like that entire interaction could just trigger as soon as I drop into the level and let me get into the platforming.
It's very easy to get chain damaged by different elements, especially if you get knocked back behind the bully by a flying witch or something so it would really help the game if there were something like longer i-frames or a slight knock-back on enemies that damage the player to give just a little bit of breathing room and allow players to recover after getting hit by something.
