Oh jeez this game is pretty hard
The good:
-Platforming mechanics are pretty nice
-Jumping and moving around normally is fluid
-Decently long game
-Soundtrack is really nice
-Art is really nice too
The bad:
-Very hard game, almost rage game-like
-Grappling hook is not intuitive to aim on the later stages (especially mid air diagonal shots)
-Spike and hazard hitbox is MASSIVE
-Sometimes hard to tell the difference between foreground and background
-Didnt fit the theme *that* well (Kinda nitpicking tbh)
Overall
Well done on this game! If the grappling was polished up more and the leniency was increased this would be an amazing game, though yeah to me it feels too much like a rage game lol. However the difficult platforming and the slow grappling hook does make it feel a lot more gameboy-y. The art is really well made and the level design is pretty decent too, though I wish there were more checkpoints on long sections. Honestly though this game is impressive to be made in such a short time.
