I think there may be two problems here:
- Lack of impatience
- Lag.
If you have lag, make sure you're not using things like joiplay or any launcher, not even itch.io ones. Also, make sure the game is not in its .zip so all files are properly uncompressed
If it's the lack of patience, most of scenes have foreplay. And earlier ones might be slow. But not TOO slow for someone to complain the way you do. If this is the case, please be more patient.
I'm sure it is just lag. XD
