i just kinda grabed the engine from my 100% pen* scrolling engine and modified it (i removed the offscreen capabilites since i thought it would be a bit less easy to use) also for some reason this is faster than @TheBaton 's remixed cloneless engine even though it basically uses the same concept but in a different way, the way i found this out was by running a repeat 450 on both this project and thebaton's project and on thebaton's project it was suprizingly slower than this one and when doing double on this project it only lagged a little bit and on thebaton's project it had a weird glitch where the "clones" would flicker through other "clones" like they were moving through layers
