Thanks for trying my game.
The submitted version of this game has some critical bugs that my prevent you from progressing at some points.
There was a time when I had to decide between fixing bugs and adding secret areas to the game, it's somehow my first jam and it seems I made a mistake by choosing to add secrets to game. Even those secrets have bug :)
I fixed those critical bugs and put the fixed version on game's page. It's completely the same game submitted here and if it counts as cheating, then you can use "R for reset" and "Backspace for menu" in submitted version when you can't progress anymore.
And no, you are supposed to go to main menu after you finish the level, so you can consider yourself as winner when you go out of bounds and return to main menu manually by pressing 'Backspace' :)
Hope you play it again and thanks for your comment.
