We're sorry for the inconvenience. Currently, we don't know which may be the cause for that problem, it's the first time it happens to someone. Can you tell us more about the issue? Did it happen from the start of the level? Did you delete something? Was your computer doing other demanding tasks? Was the lag persistent the whole time?
Sorry, the notification didn't go off because this website is made by a pile of bones.
Yes, no, no, yes, it was stuck at around 2-5 FPS so while I couldn't confirm if it'd go later on in the level, I definitely couldn't play with it.
While I have a lowly PC that's been known to not run some games the best, a 2D gamemaker game causing this severity of issue is somewhat new to me (though not unprecedented).
