I first discovered this game on my android mobile, it's an innovative Match 3 combination with Action/RPG/Dungeon crawling elements.
No fancy graphics (pixel "art"), repetitive music and gameplay but addictive, you can plan to play for a few minutes and still being clicking "one last time" on the Run dungeon again button one hour later.
The aim is to score 10,000,000 points to reach freedom, in order to do that you have to go into dark dungeons filled with mean creatures, doors, resources and treasures. Match the correct tiles at the right time to attack the mobs, defend yourself, gather resources, open doors and chests and progress into the dungeon until you're either killed or out of time.
You won't be able to earn a lot of points in your first runs but these will allow you to gather resources in order to fix rooms, gather gold to buy upgrades from these rooms (staff, sword, shield, armor and so on...), gather experience to buy new skills, complete challenges to level up and raise your resources/gold/score multiplier.
This combination of strategy and Match-3 is fun but sometimes frustrating (your success depends a lot on your luck), but you never really lose a dungeon, simply playing allows you to grind resources, experience and gold to upgrade your character.
Overall, a good game, a little time consuming but in a good way. Achievements are straightforward.
Difficulty is Ok but playing with a mouse is not as effective as it can be with a touchscreen. In fact, I think it makes the game a lot harder to play, the speed required to chain moves (as the mobs hit you but the time also slowly "kill" you) is probably more aimed at someone using his fingers to move tiles as fast as possible.
A very good and addictive game, which will require some efforts to get the last 2-3 achievements but most of them will come naturally.
