Hi quatrevingt! Thank you for playing the game and taking your time to writing me a comment - I'm glad to hear that you enjoy it for what it is (your description about it not being hardcore is just perfect and captures exactly what I want it to be).
And yes, after over a year of development I do regret not sticking with Ren'py - I also miss some of these fuctions while testing the game. Sadly, right now it's just too late to do that change. I hope it's not too inconvenient.
