I really liked this demo a lot! The characters and story were great to me, I love how colorful everything is. My only complaint/suggestion is that it's a bit frustrating the robot cannot move at all while it is falling, considering how quickly you run out of gas. However I played through the game a couple of times and it appears the levels are designed so you have to plan ahead so just ignore me if that's an intended feature lol. Aside from that minor nitpick I had fun with this and it seems like you have a good blend of mechanics to expand upon in future versions
Also thank you for skipping the cutscenes on concurrent playthroughs!
