Why is this game so buggy?

[AstroBrando]

So whenever I play the game on the later levels it will have like 20 millisecond lag spikes every 30 seconds that cause me to die. (Notice that I said 20 MILLISECONDS and 30 SECONDS.) This is especially frustrating on a level where you are stuck on a moving platform, and Meatboy will just straight up glitch right through the bottom of it. Is there any fix for this? I have tried validating the cache and all that.
