Does anyone feel sleepy when playing Temple

Every time I spend more than an hour playing Temple, I feel so sleepy that I can't keep my eyes open. Does anyone else experience this?
I think it's because there are too many flashy and explosive special effects, which are too dazzling and can easily cause visual fatigue. Moreover, excessive special effects also make it difficult to see where the characters are. I hope GGG can make improvements and reduce those fancy and dazzling special effects.

I feel like they have become a MTX first, game second company and toning down those "flashy" things cut into that business model. I don't see that being their focus ever.
