I really liked this game. The artstyle and story reminded me of old Flash games (and I LOVE old flash games). The grapple was hard to get the hang of but I eventually got it. Unfortunately, I didn't get around to beating the game because I got stuck on the level where there are two layers of spike block shooters, a spike platform separating them, and a red button on the far right. I can get to the red button but I'm at a loss for what to do next. I feel the spike hitboxes are huge and kill me when I'm not even close to them.
Other than that, super fun game and I'm excited to see what you make next!
