The grappling mechanic was fun, and I liked the 1-bit visuals too. Considering how risky the game is, it was also nice with respawn points.
A couple of points for improvement:
- In the tutorial level, the animations were not working (e.g. the mouse is not animated).
- The 1-bit/pixel graphics look nice, but you should keep it consistent. The "score" text, "pause" text, and pause menu should also be in the same style.
