Eikon	Created : 08 December 2022 Edited : 09 December 2022 2D Framework with FPS lock A good starting point for any 2D game with a text scroller and particle effects. Define your target FPS so your game runs the same speed on all systems. Also features space bar to pause rendering and long system uptime MilliSecs() rollover fix

Jayenkai	Yep, runs at a steady 59fps on Win11Arm on a MacBook! That's good enough for me (That last 1/60th.. Always that last 1/60th!!)

Eikon	Thanks for testing, Jay! It starts to get a little out of whack as you go higher than 60 but I wouldn't be running faster than that anyway. Also thanks to SoCoder for finally getting me to enable SSL on my domain, lol
