Found some strange build left in the code of the game sent to me by CrazyGamer52. Pretty primitive but I see what they got going here.
Seems to be a test room from early leftover builds. Probably a week or two in development. Some sprites are replaced, for the original was lost (Peter is using his close to final sprite here.) This one is testing objects (with a janky ball). Seems realistic enough, but needs improvement. Arrow Keys to move.
