This game is absolutely brimming with shockingly interesting ideas, especially for an 8-bit platformer, as well as just gallons upon gallons of charm. I was not expecting to be playing an action RPG metroidvania where most of the mechanics are tied to different forms you have to go out of your way to swap between, but I'm glad it ended up being that because it's a lot of fun. The remake also has really gorgeous animation and excellent music, as well as the option to swap between retro and modern graphics and sound on the fly, which is super cool and makes this pretty easily the definitive version of the game.
