hey, idk if u could fix the lag, i have done the sleep margin thing and checked the visuals c++, but it still goes a lot slower than how its supposed to go, sorry for the inconvenience, also great game.
That's too bad. It could be that an anti-virus or something is scanning it in realtime and slowing it down. I created this game in the same engine as Nuclear Throne, Undertale/Delta-Rune and Hotline Miami 1 and I understand that the same problem occasionally affects those games too. Searching for solutions to the same problem in those games might help anyone still struggling.
