Don’t worry. I never received any feedback for my game from the people who put on this whole event, lol. Very disappointed with the way the organizers handled it. Almost feels a bit nefarious (like an attempt to get a ton of people to join their discord to eventually advertise to us).
Regarding your game, I like the premise. The one thing I’ll say that I didn’t enjoy: there’s a lot of downtime where you’re just waiting for the mines to diffuse. In general, you don’t want downtime in your game (especially for such a short game project). I would have considered turning the bomb diffusal stage into a mini game (maybe you have to click at the perfect time or something like that). At least that way you wouldn’t have moments where you are doing nothing.
Also the right click to either “Show” or “Diffuse” seems a bit unnecessary. There would never be a time when you would want to “show” a mine but not “diffuse” the mine, so the pop up could probably be removed altogether.
Finally, I’d add some sort of feedback when the diffusal is complete. A simple sound effect or some small flashy bit near your score just to give that audible and/or visual feedback of success!
Either way, great work!
