Well done on making such a silly short story! There were a lot of fun moments in just a few scenes, making for a fun read the entire way through.
Although I don't know RenPy myself, I did notice the text skipping anomaly as well. It seems that an entire line blinks in and out no matter how long it is, due to a combination of instantaneous settings on how the text runs automatically. This might be fixed either by letting the text scroll in letter by letter, or by putting a longer timer at the end before it auto-progresses.
Otherwise, the MSPaint-isms added a lot to the VN's fun, goofy tone. I enjoyed the style a lot for that!
