Overall this has some nice setup, but it's a bit hard to enjoy in its current state. I think the biggest issue by far is that the level is just way WAY too big, and since enemies spawn so far away, even with the camera zoomed out, finding them is really difficult, and then it's just as easy to lose them again by falling to the ground because of depleted boost energy. I think a much smaller level, more energy, and faster base movement could help a lot here. I also think more platforms would be nice. It took me several tries to get back up to the main platform from the ground since I kept running out of energy.
I did still enjoy this though! The spriting is quite well done, and the boost effects look and feel great. The overall controls feel good and responsive too. I'd really like to try the boss level, but I couldn't clear the first level due to the issues I mentioned above. Overall, good job, and it'd be cool to see this fixed up a bit!
