This reminds me when i was kid and i played i think it was some tom clancy game i cant remember exactly, but u get beeping sounds for numbers, and each beep represents a number, so i grabbed phone at home and start beeping numbers untill i got the right combination, i was like 10 yo and i managed to pull it off i was so proud for a year lol.
2 things i had issue with, on lvl 5 u only have 1 sound, water, so i just had to guess all places near water that didnt have other sounds, it was doable but not without error. 2nd is that there is no save, i solved all lvls except lvl 9 so i just went back to try 9 again to take a screenshot but it was all gone.
now those 2 things arent really important for game jam but its my feedback.
Game UI is impressive, the fact that u pulled a map for it aswell is really giving it edge over other games, the game design is definetly a strong 5, you could've worked out a bit better room since its only 1 but i understand that wasnt necessary for the gameplay although it would look better and more polished, its a shame to have such a room next to that UI!
It would be better to count how many explosions ppl had so they dont just spam random numbers from map untill they guess right, maybe make it so after X explosions you go back to lvl one, would make it more immersive!
I did enjoy the game, i solved all levels except 9, too many sounds there made it so confusing, it starts with church sound but its not near any church i've tried all, and just skipped it at that point :D
Good job!
