Hey! This is my first Pico-8 game, a clone of the DS game Polarium.
It contains 100 levels. You can get a hint for every level if you're stuck.
There's also a level editor, which lets you create your own custom levels. You can even share levels with other people with 30-digit passwords. These passwords are completely compatible with Polarium, so you can also find lots of levels other people have made online for an extra challenge. 20 custom levels can be stored.
