Really well polished game. Nice one

I liked the puzzle with grappling hook, how it has a "time bullet" effect when firing the hook so you can control when and how to use it. Also, how it can be fired in multiple directions and how you can move some objects, in some way felt a bit intuitive.  The difficulty of the puzzles grow too fast for my skill xD. Great entry!

this game would be great on a larger scale

Liked the combination of a platformer with puzzle like situations. The music was nice and insane cover art. Level design was really good too. Congrats!

Great platformer, though I only managed to get somewhere near the end of the 2nd level before completely biting the dust lol.

The presentation is absolutely awesome. However, I do feel like the hitboxes for the grapple points could have been a little bigger just for QOL. I also felt like it wasn't clear which platforms which you could actually grapple to.

I also found a small bug where if you touch the absolute top of the screen but there's no room above you, the screen transition happens. Still, this is just a small nitpick lol. Amazing entry

Some outstanding level design here! Also loved the art and the music!
My only complain is that the game could have benefited having a way to see the room layout in advance, something akin to Celeste's Binoculars. 
That said I would love to see a full fledged version of this!

Very tight controls. The grapple felt easy to learn and very fair with static objects. Once moving targets start showing up, the difficulty ramps up really quickly. 

Excellent presentation, love the main character design!

Really fun game. The controls are TIGHT and I love it. Art and audio are both really good.

Very cool game. Wish I had better hand precision for it haha. Well done

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.

Very fun gameplay!
