I do enjoy these type of games sometimes. 19XX, Akai Katana are examples, especially when they have huge influx of bullets to test my reflexes with lol. But yes, solid entry! it took a while to test because it was quite heavy, I'd admit hahaha.
The gameplay is good, but it's quite difficult to dodge incoming bullets, which made it tough for me to survive longer but for a Solo dev first jam I think you did quite well!
