It was intentional, I confirm. I figured considering what little text the game had, I could get away with using a very stylized visual effect. It's really the only game of mine that goes that hard on the PSX texture warping aesthetics, for diegetic reasons, mostly.
I'm glad you still enjoyed, nonetheless. If you acquired Please through the Equality bundle, know that you also have access to the sequel/prequel/thingie, Please Follow. That is, if you are curious for more of the same universe.
