As a few noted, it's feels very fun to play, but as far as metroidvania goes, especially content-wise, it's quite lacking. There's little to no exploration in the game, none at all whatsoever on the main path, it's extremely linear. It's very short, not even half a dozen hours to 100%. Map is also rather uninspired and uninteresting, it's just a big rectangle with every pixel filled in with a room and you have the map, one big solid block. It also just very easy, overly so. It's a fun romp, but don't expect much from this game, most other metroidvania offer quite a bit more than this one does, but for the cheap price it's still fun to play
