Hi, I got the game today and I've been really enjoying it for the most part! The only thing that's been really putting me off is the fact that the game seems to lag a lot. Most of the time, the game is either running at full speed or sinks to around 2/3 speed (I can tell because the speedrun timer starts taking 1.5+ seconds for a single second to pass), and the transition from fast to slow seems to happen almost randomly. On the other hand, the transition back from slow to fast seems happens one out of every five or so times specifically when I die. I've tried every combo of graphics settings (windowed mode on smallest size, no vsync) but it does not seem to affect the problem in any way. I'm hoping that it's just a bug and not my computer being a toaster (which I'm hopeful isn't the case). If anyone has had a similar problem please say so.
Edit: after doing a bit of experimentation, it seems that the game only speeds back up sometimes if I have vsync enabled, otherwise it seems permanently locked at a low speed.
