It's a really cool idea! Watch out for AI mistakes though, especially when generating content in a foreign language. I see one mistake in the "Time Short Form Game" image where the image has "habl" for what should probably mean "halb".
Also, I'm not sure if converting between 5 digit numbers and words is a good starting task, unless you want to dive right in with German's (in)famous word chaining ability.
Yep, I noticed AI is terrible with words on images, and that seems to have slipped my attention. Thanks for the callout! I tried to keep the number games tamed by only going up to 3 digits.
