Hi thanks for playing my game, I can definitely see how a mine sweeper style mechanic could add an interesting layer to the game. Maybe it could work as a powerup in a future update or version. I appreciate all the ideas, I wanted trap key to be more about making decisions based on memory and wanted some element of luck too.
To be honest I'm not the best developer i still have much to learn. My hope is to inspire others to make games be it beginner or seasoned. I believe the most important thing is to keep experimenting and having fun in the process and if it's given you more ideas then that's awesome.
