10m dungeon as you said.
Also horde of heroes A game I frequently play.
So basically, yea. Adding additional game-play mechanics to a match 3 game is viable. Probably the better route to take. I'd make a list of things to match with a match 3 game (HA! puns). and maybe design them out or make quick prototype and see what feels right.
Thanks, but those weren't it. I was able to retrace my old games with the Google Play Games app. It's called horde of heroes but the ones you linked have better ratings so I might as well try out 10000000
