Thank you for playing!
Regarding the art, I don't consider myself an artist so thank you for your compliments. Maybe my next game will be a bit more vibrant.
For the jump, it is actually a little bit more forceful than the launch, which was supposed to be the reason to use it, and it does always go straight up which can make it easier to use than the launch (which resets your momentum, making it poor for a jump if you aimed it straight up). I think with some tweaking the jump could be more worth using, and I agree the launch is generally just better, especially for this level design.
If I ever return to this game I might make new "towers" as different levels. I was thinking it would be fun if the towers corresponded with a different TTRPG monster, starting perhaps with a goblin and then ending with a dragon. Then they would require higher and higher rolls to "beat" and move on to the next level.
Thank you so much for your feedback, I appreciate you taking the time to help me improve!
