Really fun! The soundtrack was awesome and had me headbanging in tune with the rhythm a little bit haha. The ship control felt nice, decent movement speed and fire rate.
I wish you could fire with the spacebar though, I played on a laptop with a trackpad and it was a little awkward hand positioning for me. But the shooting felt really satisfying especially thanks to the sounds effects.
The difficulty progression was nice. The first boss was really easy (you can just stay in the middle of the screen and he can't hit you) but it bumps up nicely in level 2 and again in 3 (i died in 3). The attack patterns good and had me moving around quite a bit which is just how I like my shmups. The gun meter to prevent spamming was also a good touch!
Great game overall, I enjoyed it!
