Handprepped assets are always cool to see! Nice job drawing the space ships. Though the gameplay is simple, there was depth to the design (e.g. multiple enemy types with different hit points). The feedback from landing hits was good, with sfx and particlefx. I was pleasantly surprised when i picked up the multi fire upgrade, it felt really strong. No encountered bugs as well.
I was slightly confused by not being able to shoot enemys that went past my "floor", not sure if that was intended.
Overall, solid entry!
