I really, really like the fast drop downwards mechanic. You can really get a good parkour flow going! I think things like jump pads should set Y velocity to zero before applying an addforce upwards (in case the player is falling down onto the bounce pad). I caught onto the controls pretty quickly, but could see how others would struggle at completing the levels. Definitely would make some stupidly easy fool proof levels to start for the average playtester. Otherwise I love the aesthetic of the game and the levels were well thought out. It was a real blast to play. Sorry for the novel, but last minor issue I ran into was difficulty setting the screen resolution to what I need (came out real weird on my ultrawide monitor and had to do some command line magic to get it functional). This is all to be constructive as I know this was just a demo, but was really a blast to play and a beautiful demo! Loved it.
