Thank you for the kind words! I'm still practicing my pixel art skills, I'm glad you liked them.
It's a very free-flowing kind of game, the grappling hook may only have 2 directions to shoot but you can gain lots of momentum and scale the tower super fast. Check out Celeste Classic 2 (which inspired this game) if you want more of it! Appreciate the attention towards the telegraphing of abilities too!
Oh, actually, I saw you play my game on your Twitch stream just now and I appreciate it! Sorry the game crashed for you at that moment, but fortunately that is indeed the ending of the game. The unusual high jumps are a bug, I had another player test it and they reasoned it was probably a monitor framerate issue.
Thanks for playing again!
Here's what the end screen looks like:
