If DigitPenguin is still working on this project or wanting to work on it again, it would be nice if these could get added:
The ability to switch the music played in the level.
A new demo level.
A way to make custom terrain.
An item that will give Madeline 2 dashes, like the one in the Pico-8 game.
An option to start Madeline with 1 dash or 2 dashes, like in Chapter 6: Reflection you start with 1 dash, in Chapter 7: Summit you start with 2 dashes.
Maybe a screen to select pre-made maps to build off of?
