Ok so I find it funny that your game didn’t last 20 seconds from start before failing my first bug test.
The wall on the left, right at the start, can be climbed by mashing the jump button and running into it, and you can walk over it off-screen and fall into the void, causing a softlock.
Is a rather normal issue in most plataformers to have. Try making it so the wall is not recognized by the game as a floor, altho it might by tied to the tile block that you maybe used as terrain too. If so, try making an invisible roof. Aditionally, you should add a death zone, so if you somehow get to bypass that wall anyways you don’t get softlocked.
