It's true that optimization is quite bad for this game. This is something I'd really like to fix in the future.
if youre planning on adding more features/secrets any time in the future, I think a bonus "ruined orgasm" finish would be a neat secret, for example, if you manage to get at least c rank without doing any bounces (say by getting 10/10 on the slider) or maybe by getting all your points early and not doing any bounces in the second half of the run, then it would play a cum scene where kuraksa looks angry and doesnt stroke during the ending, you just cum while she stares at you
