Note: It took some time for me to get back around to finishing comments on the jam games. Pardon the late comment!
I had a lot of fun playing this one! The gameplay alone is very smooth, with a variety of controls and a well-balanced challenge. The only issue was that it was easy to get blindsided by foes coming in and then take instant hits (especially near the level's edge). Otherwise, it was easy to make out everything and figure out how to work around that particular case.
The visual style was also a lot of fun to look at, especially combined with the music & audio. It helped make for not only a colorful arcade game, but also a very well-playing one overall. Thank you for making this! ^.^
