No biggie! The fact that you attempted to make a game in 3 hours, and still made something is commendable. I used to think games took days to make, and here I am popping out a really simple thing in just a few hours.
The benefit of this experience moving forward is that one can assess how one did, identify any pitfalls, and then try again for the next jam; taking the wins from the previous experience and avoiding the falls.
