Thanks for the feedback. I understand that the difficulty is hard. It is the difficulty I play on. I will consider this next time I enter a jam, for sure.
The gimmicks (aspects as you mentioned) include
- The bullet's role of damaging the player is reversed. (Healing bullets)
- Swapping the roles of the health bars between the player and boss (with a tiny stretch of the imagination i would call the reversing the roles)
- The final phase is, actually similar to your game it seems. Where you are the boss, but you also control the bullets. Reversing the roles of the bullets dodging you instead of you dodging them.
