Had a bit of fun playing this game, as I'm familiar with rpg mechanics and metroidvania kind of games. I like the design approach of signalling to the player what obstacles are there and what you may need to get them (i.e making ledges too high so you need to double jump, having ice barriers so that means you need a fire power up, etc).
It caught me off guard because I expecting a very simple rpg platformer but exploring around was fun. The only addition I'd give the game is maybe a variety of enemies? Combat became repetitive halfway through the game.
