I really liked the story and youre game fits well together. As Feedback: You should use a Spriteatlas for youre Tiles, just google it:). It removes these white line glitches. Also, your wall collision counts as floor, because you can jump on walls and can go out of the map sometimes. To fix this, put all walls in a different Tilemap Layer as your ground and then just dont give them the ground tag (as I am assuming this is how you make this work). If you need help doing this just write me on Discord my name is identical (I am in the Brackeys Discord). You can still fix these Bugs in the next two days, as fixing bugs is still allowed for two days after submission ended :)

I found a secret hidden place :-P
