I really liked the art, although CRT shader over the instructions were a tad hard to read. The controls were sweet, definitely was hard (although not target audience) but playing on a controller was really nice addition.
We spent a lot of time trying to make the controls feel as comfortable and responsive as possible.
As for the instructions, we're taking note of all the feedback and are already working on improvements. We'll release a more polished, definitive version once the jam is over.
