This is honestly such a great game, it deserves way more ratings. Super polished, original and fun to play, really good job. A tiny bit of constructive feedback:
-I would have liked the difficulty to ramp up a bit faster as it was quite easy to figure out where the 1 was in the first few rounds which made finding the other numbers easy as well. I think it would be good to force people to use items sooner.
-Item tooltips.
Two very very minor things but apart from that it's such a good game, really well done.
