Heyy! Thank you for your positive feedback!
Congrats on finishing the game too, I might have made it a bit too long for a game jam haha
About the screenshots you sent, these rooms are in fact impossible rooms. So you did in fact encounter rooms where there were multiple solutions.
The first one was A(1) - B(5) - C(5) but could have been A(5) - B(5) - C(1) exactly as you said ^^. Since there are multiple solutions, it is an impossible room, and that would have been a good occasion to use the magnifying glass from your inventory
The second room you made a screenshot of also has multiple solutions, thus making it an impossible room too
Don't hesitate to ask more about it if I wasn't clear enough!
It's actually quite impressive that you never really had to use items in fact, because you're supposed to encounter a few of these rooms in a run, so I guess you must be pretty good at the game :D
Also, a few comments for this entry suggested me that it would be best to remove impossible rooms, but then it makes the item system a bit pointless... I'm not sure about I could have handled it, but if you ever have any suggestions, I'll be glad to hear them :D
Thanks again for finishing my game, it means a lot to me, especially since it's quite challenging as you said :>
