Hey! First of all, congrats for your submission! I really think the intermitting light is a good design idea for a plateformer. Moreover, you link it to the moles blindness, so it's pretty cool!
I would advise some fixes:
- Play the sound of jumping only once when grabbing walls.
- Put a speed limit to your character (when grabbing a wall especially).
- Don't use rectangular collision shape for your plateforms as they look more like triangles.
- Set your character x speed to 0 when respawning (I got a bug in Fallen Thoughts: I died when I was moving and so respawn with a velocity and constantly fallout outside the first plateform).
- Maybe you should write "Restart" on the button at the end?
