Wow! Love the visuals, sounds, music, and animation. And the movement is super fun. Feels extremely polished.
It's very cool the way you can chain together dashes and grapples, zipping around without needing to touch the ground. It feels great. One thing though is that after the first room, I never needed to use the wall jump. It'd be cool if there were some platforming segments that required you to use your full move set and maybe restricted you from just flying through.
It's also a bit linear, as the grapple upgrades are nice but I never really felt like there was something I needed to return to later. I kinda just found the keys as I went along.
Minor gripes though as this is overall very impressive. And replayable, being short and having the speedrun aspect. Would love to play an expanded version.
