You still felt pressured? My goal was to make it as chill as possible. Most playtesters really appreciated the auto-adjusting difficulty, did this not help you or was the balance off for you? Anything that could help you make it less stressful?
The auto-adjusting works by adding/removing items (and maybe adding multiples) I guess? I think that worked well.
Maybe I'm just sensitive in that regard; timers in thinking games make me anxious. :D
