On lvl 4, you can soflock the game by going left from the starting point. Having a "give up" option in the in-game menu would help.
Yeah, sorry that shouldn’t happen in the first place. I forgot to add a wall at the end of the screen there. I would rather add a function to bring the player back to the starting point when they go out of bounds.
Also, I have a friend who plays a lot of platformers and that crazy kaizo mario stuff, and he gave me some honest feedback. So I’ll create completely new levels. If issues like this persist, I will let players have the option to use dev tools. With those, you can restart levels and stuff.
