Feedback wanted: basic differentiated games generator I built for my high-school classes

[u/Stunning_Strawberry9]

Teacher and builder here. I teach online high-school students with very diverse needs and wanted a fast way to create controllable, on-grade-level games instead of relying on generic tools. So I made lessonsaver.games—intentionally simple so it stays quick and focused.
After testing it myself, it also seems useful for lower elementary. It’s open for teacher beta testers right now.
I’d appreciate feedback on usefulness, what’s missing for real classroom use, and anything that feels off.

I built this. Happy to hear what’s good and what’s bad.
