Apologies, I did not make the artwork. Most I did was modify someone else's stuff for the calendar. I forgot to include the links for where I got assets - I've updated the game's page to reflect these now though. For the character art, it's from Ddant1100, there's a link on the game's page now.
You can learn new skills later - part of the MC only having "Lecture" for his first round of teaching is 100% because he's not really a "teacher" before he arrives. He doesn't know what he's doing, so all he can really do is talk at the students rather than actually help them. Was going for a, "show them mechanically he's a fish out of water" sort of thing, lol. Though thinking about it, at the very least he should know how to take a break even without knowing the job.
Hearing you talk about the garden had me like, "What, I never had those issues testing - wait a minute. Did...did I ever test the gardening?" No. No I did not. How embarrassing, lol. I'll take a look at it again, see what's going on there.
I have no idea what's going on with the saving. I never really checked that either, tbh...never touched anything for the save files, so it didn't occur to me that it could go sideways. I'll take another look at it.
Anyway, suffice to say, it's got a lot of issues for me to fix, lol.
