Lots of fun there :)
I think having the time cumulate or something would help give it a difficulty curve - and I really missed being able to move diagonally.
Thank you! Part of the reason behind the 4-directions movement was to give it a bit of a retro charm, like the good ol' "move on a grid and push squares" games, but also so I didn't had to spend time rotating the sprite and making it look pretty!
