Thank you for the nice words!
And thank you for the feedback too, it is very valuable! Post-jam there may be a toggle for the trail, or I may change how it works. Currently it is rather bright and can easily obscure the ship for some players. Sorry about that!
It’s also true that firing in a circle with upgraded weapons or running around in a circle - not sure which you meant - are both effective strategies in this game. It’s something I would like to change, to keep the game more interesting, especially at high stages.
The balance is quite poor on some things, but I ran out of time to try to fix them during the jam.
