Yeah. I'm a little late but I did it.
I finally give up unity and I'm working on Renpy.
And I feel really stupid. I didn't do it before because I thought it was too difficult and I need a lot of times to learn a lot of things...
Surprise. It ain't that difficult.
I'm rebuilding episode 1 and adding episode 2
With Renpy I solved my issues with savefiles and saveslot, my issue with gpu usage and my issues with frozen/still image.
Damn I could did it one year ago.
Anyway... The game is coming. I'm doing my best to add everything faster as I can.
