Thank you for the kind words, our team worked quite hard during the course of the jam. Also I'm happy to hear that you found the pacing and length good, puzzles are very difficult if not impossible to balance for everyone so I think that means you're pretty much the target demographic for this level of difficulty haha.
Oh and thanks for the feedback about the pause menu. This was something we added post-submission and I think the cursor bug just got overlooked. I assumed it was a web browser issue but I've since confirmed it also appears in the windows version so I'll have to ask our programmer to take a look at getting it fixed so thank you for bringing it to our attention.
