It was a lot of fun, but I wish the difficulty had ramped up a bit faster. I loved the particle effects, though. The way they bounced off the player and enemies made the kills feel really awesome.
Yeah I know. There's actually three different enemies and they had different flight patterns and characteristics, but I just overslept too often and couldn't get them in the final cut. The code was there but I really struggled with making a proper difficulty ramp. Lessons learned I guess.
