It’s fun, but the music is too loud and it’s too chaotic. Having a lot of stuff on screen is fine, but it would really help to think about how you can make it fair for the player. Waves are too fast, so even if I only focus on that most of it simply cannot be dodged.
Also I don’t think there is a way to get more damage, and the enemy has 5000 hp. Each hit is 5 damage, there is no way I hit the boss 1000 times. Usually it’s a hint there is another way to deal with the boss, or the fight is impossible :)
Cool entry though!
