Enjoyed this a lot, especially the art and the unique concept. Sometimes it felt like my character got stuck on buildings/other environment when he wasn't touching it. Not sure if it's just a collider size thing or my own bad skill. I'll have to keep trying.
The limitation "must go up" is kinda funny in this one. You will, eventually get sucked up by the UFO, but the struggle is trying NOT to go up. I chuckled at that little twist.
