My first platformer

This is such a great game!

Good cover image: moody and distinctive. Being fond of squares and cubes (maybe little hexes too), I tested this one just because of the image.

I like the minimalist style and clarity. Tweens and transitions are polished. Instructions are clear and don't interfere with the gameplay. Game flow is good, as retries start immediately after failure. Jumping seems to have a little delay, but I got used to it.

Some minor notes:
- It would be nice to see the level number when starting one.
- As the game is played entirely on keyboard, consider making menus to use keyboard in addition to mouse.
- Checkboxes seem to be inverted: filled ones are off, and empty ones on.
- Chromatic aberration feels unnecessary in this context.

I suck at platformers (this one too), but I enjoyed still. This is quite an achievement for the first game (to be honest, I don't believe it is the first).
