Sure I had fun! This game jam business is an awesome opportunity to see what other people are capable of delivering, but most importantly, you surprise yourself about your own capabilities under a strict deadline! I tried to give constructive criticism to every game I played, so the developers would make even more fun games in the future! :) Another tip: dev 60% of the time, and PLAY-TEST 40% of the remaining time, and also give your game to 30+ people for early feedbacks before the release. I did so, and my game is 30% different than what I planned out before I got all the valuable feedback from my dear testers. 1 man can't get it all right, I mean look at how dictatorship turns out :))
