I'm not sure whether I'm missing anything with this game, it could really benefit from a tutorial or even an Instructions menu. I found I could just hold 'W' and ever so slightly adjust my position if I saw something on the minimap and get to the top pretty easily. I'm not sure what the point to the energy bar is since it seemingly does nothing, runs out really fast and as far as I can tell, there's no way to restore it. Racing the AI to the top while shooting them to slow them down could be fun, but they start ahead of you and I don't have any clue how to catch up other than holding 'W' and avoiding everything which still wasn't enough for me to beat even half of them.
The aesthetics, sound and idea are nice though. It's a solid entry, good job! :)
