Hm, I played on Firefox. Because that’s how I roll.
I couldn’t figure out the mirroring (it felt wrong). Even smashing all the buttons did not work :-D (I realised that I could click a flip twice, but then my virtual laptop burned).
The UI was not responsive. Using the entry randomizer of itch.io cut off the chat. Due to autoscrolling I had to move back and forth to see all moving bits.
What a bummer!
