I really liked the gameplay. Nice work! Theres a few submissions with a sword swing like that. Not seen that anywhere else. I did collect upgrades but I felt like I lost them all when I died, the speed upgrade is the most noticeable one. The cooldown is a little tough in the beginning, especially for the amount of spawns. I found the boss joins from the left of the map, and I can attack him, he doesnt attack until he is in the middle, but had to dodge all the spawns, but was funny to see that. I didnt like the fence area as it blocked the view of the player. Boss kept killing me, my only tactic was to upgrade the speed to dodge his bullets
