Talking about bullet hell, there is a concept i am developing since the last game (Kaleido Combat). i am making the enemy mostly focus on one layer at a time, which means player can dodge the bulley simply by jumping. It's still in trial and error phase but it will be my direcition future. But as i say, i havn't tested enough because i run out off time, I bascially finished the "ending" 3 hours before deadline.
For the character and setting, thanks for appreciation. There is a world setting in my mind but i wonder how many game jam i need to tell the full story.
