This is a fun picross game, with an RPG theme loosely pasted on. I didn’t feel the theme, but that didn’t matter, because I still had a lot of fun and the game looked very nice with this theme. It is most of all just a picross game, but you have 3 lives and monsters will attack you when you make an error in the puzzle and after every few minutes the monster(s) attack. You can buy 2 more hearts during the game to make it easier.
The achievements in this game are nice: you get around 80% of them for just playing all the levels and use some of the in-game items, like health potions or spells with different effects. The grindy one at this moment is getting 5k. I highly suggest getting that one before buying any health upgrade, because the health upgrades cost 1k gold each. That means you’ll have to grind 2k more if you bought the health upgrades before you unlocked that achievement. To get to 5k, just play the game as far as you can and enjoy it. When it gets too hard for your taste, go back to the beginning and keep completing the star level which gives 10 gold for every time you complete it. You can complete that level in a few seconds. As stated in the list above, the developers might change that achievement to make it less grindy.
