Thanks for playing!
I'm actually glad to hear you wanted more areas to use some of the abilities. This game ended up being a rough prototype of what I had originally planned (you can kinda see some of it in the background of the final room of the tutorial, the whole city on the other side of the door was designed to be one of many playable areas, I just didn't have time to finish it), so I might still make a complete game with these mechanics.
If by red ability you mean multidash I had considered using it as a way to catch yourself midair, but that would conflict with the airdash which is an overall more useful platforming tool. The multidash was originally just added to give the player an easier way to paint surfaces red. I may reconsider how it works in combination with the airdash though.
