The art looks nice! Unfortunately I struggled with the controls because I couldn't figure out how you were supposed to "lock" a number in place without detonating the bomb, and I think the game would have benefited from a proper tutorial. :(
I did specify the controls but I get why you couldn't figure it out properly. When the module arrives on the correct number you're supposed to hit enter to lock it in. I didn't allot enough time to work on the UI and tutorial. Anyway thanks for commenting!
