It seems that we are overestimating our abilities with our plans.
So I must unfortunately state that we are not able to add other playable characters. However, Bibi the Bunnygirl is still Chiro's first best friend and instead will be Chiro's first super attack.
Currently, she functions as a heat seeking bunny missile that you can call upon to deal heavy damage to an enemy.
Additionally, most of the game's restructuring and refactoring is done, and the Octo Boss is in a better working state than before, and we are making preparations to give her-her own CG Scene.
I cannot give a exact date when there will be an update, (mainly because giving a date ALWAYS backfires) but what I can say is that we are in a good position, and that we will push an update sooner, rather than later.
