Note: I originally rated this a 2.5 because the web version didn't work, but as promised I've bumped up the score now that it's fixed.
The controls certainly took some getting used to, and it's pretty disorienting at first trying to fly around while going so fast. The fact that the gun recharges when touching a wall or the underside of a platform also meant that I could cheese some levels like Tree Stumped really easily. That didn't diminish any of the fun for me personally actually, I love the feeling that I've outsmarted the game.
I liked the level design and aesthetic that's reminiscent of Monkey Ball. It made it feel familiar to me, but it was used well with the flight controls, though some of the precision platforming was a bit frustrating. I could just be mad cuz bad though. The soundtrack was good, and the designs of the characters were really cool.
Overall I enjoyed the concept and gameplay and I'll probably play through the rest at some point, because I want to see where the story goes.
