Way too early to limit play and/or pay
Like others have said, it is a good start. Two minutes? NO! There are issues. I wont even keep it on my machine long enough to test future fixes. The physics are horrible. Strange and impossible angles from the flippers. And the ball goes through the flipper sometimes. Not yet ready for primetime. With a little spit, polish and careful examination of what you give for free and what you charge for, you might actually have a winner.
You should give away this table for free… then fix it. Make other tables with your core system and then sell them as upgrades. You "could" get my money if you did that. The current way? You will never see me upgrade or purchase. Sorry.
