but having to click spank every 5 swats on something that's already set in stone is dull

I understand your point but this option is here for those who likes to remove spankee clothes gradually at any point they want, not just at the start. I prefer it this way but if I get a lot of negative feedbacks I'll think about some resolution.

one puzzle where you can complete it in a way that softlocks you, so...

This is also intentional. There is 'Z' button to give up just for this case. Maybe I'll up the reward, not sure yet. I need to adjust economy anyway. This puzzle has only 3 rooms for now, it would be boring to did them a lot anyways but for early game econory bigger rewards will be too much. Next rooms if I deceide to extend it will give you better rewards... or there will be no more rooms and you just unlock other quests with Tora with more fun stuff.

What are those "*.png_" files

It's ususal png files but encrypted by game engine to not allow player just watch images in folder and actually play game to unlock them

There is no hints to develop game faster besides experience. In terms of arts - I have a software 'spanking image generator' which is now in development state. You can use it to get arts for the game pretty fast when it's ready. If you agree to terms of use.
