Just starting, so I can't comment on the game itself yet, but I find it jarring that, in the Itch Desktop App, the files are set up in such a way that "installing" the game apparently just downloads it, and you "launch" the installer, not the game itself. That would normally be an annoyance, but in a coding game, it feels a lot more wrong. Maybe someone needs to poke the install package?
Ah, does the Itch desktop app not play nicely with msi? That's too bad.
I liked the game, especially the fact that you don't go straight for teaching literal coding so much as the concepts needed to be a good coder. I'm considerably out of your target demographic, but I pay attention to such games, as well as enjoying them as casual gaming. So, well done!
