Overall pretty fun, neat game!
The bars for health and stuff were a stretched oval? Was that intentional? Maybe make them all rectangles. Also there were some issues with overlapping 'plane'ts or whatnot, but that didn't hinder gameplay at all.
I began to understand the game as I played through but maybe a SLIGHT intro would have helped a lot.The nature of the game did bring some cool moments though, like me holding out just until the cargo ship could come and deliver another major wasp and fleet. That was pretty cool.
A great addition to this game would be more ships and fleets to control with different specialties (more health, speed, attack, attack speed, etc) but for sure you have a strong baseline.
The sound was really good, and the graphics were very pleasing as well. Maybe the UI could be polished, but it does its job. I especially like the environment and the ships on both sides. A cherry on top would be to add animations maybe to the ships, but that might be an unnecessary addition.
Great job!
