Noser from #4tt made a new game in Java every day for the month of June. They're all really entertaining. Since it's June 30, he's finished today, so now's a better time than ever to check them all out. They're all quite diverse, so if one does not pique your interest, a dozen more will.
Check out today's for a "credits sequence" - it's almost Katamari-esque in that you somewhat interact with the credits - and it credits people from #4tt for silly things like QA and ideas. But Noser did most of the work so there you go!
