Pretty fun! I know a lot of people are mentioning Katamari but i immediately thought of Attack on Titan honestly, a much of a stretch as that may seem. Fighting big guys with two grapple hooks and a jetpack move thing like I saw a connection lol. But yeah growing stronger and stronger and flying around was pretty fun. I do feel like there could have been more visual indication of the various levels of power, like something to show how much more powerful you've gotten. Good work!
