Wowww!! Super impressed with aspects of this game that often get neglected in game jams. It had interesting environment art and level design, great art direction, fun dialog, and a meta-narrative that caught me by surprise (not gonna spoil anything ;))
Visually, it was very polished. I could see this style being used in an actual game release. Building a few levels was a great way of keeping the exploration interesting. I like that each level had it's own visual motif that you could see from the overworld. Definitely gave me some Mario Galaxy vibes.
The character choice was a fun addition, though I would have liked to see it impact the gameplay a bit more but kudos for including it -- yet another feature I haven't seen in most jams.
For audio, it was definitely consistent with the chill synthwave aesthetic that the rest of the game leaned on. I liked how the different characters had different "voices" too.
The enemies didn't pose much of a threat, so I viewed them more as "collectables" or something to encourage the player to move around and explore the world. I lost track of the flying guys a couple of times so maybe some kind of enemy radar or sound effect when they're nearby would help.
One suggestion I have is to add more mechanics so the player has something to do in addition to flying around and finding enemies. Maybe some kind of resource scavenging (e.g. for power to enable increased movement that allows for more level navigation, or weapon ammunition)? Or puzzles?
Overall, I was extremely impressed with the polish of this game. You guys did a great job with this one!
