well done sir
However there are a few things i think you need to change.
1) When Encon activates the demon form, it leaves him open to attack in boss battles. Why not make it so that time stops as he switches to devil form?
2) Celcius is way too hard. Her combo breaker does like 300 damage. Thats alot more powerful than any of her regular attacks. Plus she uses it all the time so it unto itself defeats its purpose.
3) Make the his pistol machine guns slightly more powerful.
But yeah, excellent game. Can you give me any tips on how to beat Celcius?
