There is some variation in the platform speed across levels, but having seen some people play there is a lot of start and stop and I agree that it messes with the pace of the game having to stop and wait so much.
I have never invested any time in learning to do my own art. I always choose a pack and then work within its limitations to accomplish my goal, but yes I am aware that some asset packs get old/boring when you’ve played so many games made with them.
Thank you for the insight.
