The idea of matching two different games is nice, however need to see a more complete version in order maybe to have a though choice. The normal minesweeper is more a calculation or logical choice instead of a "taking risk" dilemma, so that's why a more complete version might give more chances.
I noted some points that you might already be aware of, in case you have missed them:
- Screenshake option seems not working, maybe it's not implemented?
- I guess Audio option is missing too, I can't do anything clicking on "Audio".
- Be careful to disable underneath buttons when Option screen is open, I can click on "Credits" and the windows pops up above the Option window.
- Collisions for Gold and Chests should be larger, it's hard to select them on PC, I can imagine how it's risky to play the game on a small mobile screen.
- What's the point in attacking the Goblin? I did only one battle with 30HP and I died. Was the battle supposed to give more gold if you win?
- If you have time, having feedback to understand what's going on during the battle would be great.
- When the Goblin hits me, it gets a floating green. Shouldn't I have a red -5 flying above my character instead of the Goblin getting +5 on it?
Overall the idea is nice, but didn't see much implementation of the RPG/strategy game part. I'm not a fan of minesweeper, but having the fantasy part added to it might help in creating interest in players like me.
Nice start, keep going! :-)
