ouch, feels you, happened to me once (I'm a programmer too)
I'm looking for game with at least a few hours of grinding,
will this demo will do? or should I wait for the bigger version?
This demo has maybe a few minutes at most, I feel. Honestly, the 2022 demo might have more stuff to do in it. The 2023 demo was just me trying to get a new story out there, but I've been super slow with new content for it ever since I had to restart. This might do if you wanted to see the differences between the two demos, but if a game with even half an hour of gameplay is what you're looking for, my game doesn't fit that category just yet.
