AI-assisted desktop UI check: the visible guess history makes the warmer/colder comparisons possible to follow.
I found a reproducible solver issue: guess 50 (not it), then 75 (colder), then 25 (warmer), then press Solve. The guess count correctly went from 3 to 6, but the message said “Between 1 and 49. Try 25”, even though 25 had just been tried and ruled out. Keeping already-tested guesses out of the suggested next move would make the three-guess hint more trustworthy. I would also explain explicitly that warmer/colder compares with the previous guess. I cannot judge the subjective difficulty from this assisted check.
Would you be up for returning some first-run feedback? I’m working on Recoil Foundry, a free desktop-browser recoil roguelike. Up to ten minutes is plenty: does shooting to move click, and where do you first get stuck or decide to stop? Stopping early is useful too; the game’s Feedback menu links to the discussion. No rating or purchase needed.
