The ability to pick platform types when you die definitely adds an interesting puzzle element to Digress.
The art is quite reasonable with the palette limitation and the animation is decent.
Movement feels a bit sluggish and the jump a tad heavy but it's fine for the most part.
There's a slight physics issue where you seem to stick to walls and such but it's bearable and doesn't ruin the game.
The music is nice and the sound effects are good, though I think there could be a sound effect for jumping.
The main menu works fine although highlighted options don't stand out enough and there's some spelling/grammar errors like "Bubbles" being spelt as "Bubles" (assuming that isn't intentional) as well as the mouse cursor showing in normal gameplay and not just in the menus.
Generally quite well done, Digress mainly just needs more mechanics/puzzle elements and more content and overall polish.
