Love this game, and appreciate the developers! I'd give this game a solid 4/5. I've played the free version for a week or two, after which I decided to purchase it on Steam. Even though from the very beginning I knew that one of the maps (Forgotten Castle) lags like there's no tomorrow -- I still opted to buy the game as a show of great appreciation for the game you're cooking there, my dev bros. My machine isn't powerful, but I have absolutely no problem playing in Goblin holes or the Frozen caves -- the castle is the only place I have this issue; and not just the occasional freeze, but constant nagging lagging, which results in me having played on that map only thrice throughout these 30 hours, or the 40 more that I've played on the EpicGames version.
Otherwise -- most brilliant of games, and most brilliant of concepts. There's nothing quite like this experience, especially after you learn that none of the gear, even hidden deep in your hard-bought stashes is there forever. The game does a rollover every so often, and everybody has to start with absolutely nothing, and once you learn that -- something sparks in you. There is something absolutely visceral in the realization that the potions that you hoard for 'a later more important dungeon' may just one day disappear without ever having been used. Then you begin playing the game with actually having fun! An absolutely lovely touch!
If you like hard games that reward learning the complex (but comfortably so) mechanics, but also enjoy the goofiness of jolly cooperation, and the occasional toxic backstabbing -- this would be your cup of coffee. For tea will not sustain you during the long nights you might spend playing this gem. Just please, for the love of all that is cute in this world -- optimize the third map.
And please, don't abandon this game, it has some rare potential
