Thank you both for playing!
We were aiming to do a game this simple because it's our first try in Godot. As for the chromatic palette, we designed the game at first to have two levels, so in order to create different biomes, we created different palettes for each level. However, we could only finish one level, so at the end the first level might seem chromatically a little out of place.
As for the jump, we've been also told that, so we will take that into account!
Thank you again!
