Unfortunately, I'm having a lot of problems with that atm. Cloud build isn't working and I even managed to get a laptop and it just won't import.
We'll see about next release.
Optimization is hard mid development, the biggest issue on mobile is actually memory which I think feeds into the FPS problem. The more the game expands the more memory, assets and other things loaded which seems to increase burden.
These things are fixable, but they can cause problems while things are still worked on. I can only do so much for now, but I can promise by the time the steam release comes or probably shortly after, some of these optimizations will be implemented to better control memory usage. Along with some things like broader LOD usage is also on the horizon.
The idea is to create scenarios for more varied conclusions, without the limit most players would only ever see one or two conclusion scenes, or engage in longer sessions rather than progress time which will be needed to unlock/progress content.
Limiting the cumming encourages some degree of strategy while also pushing progression.
