8 doors is a very complex 2D but fun metroidvania/platformer, I wouldn’t recommend it for someone that is starting to play theses types of game since there’s a lot going on with the control (changing weapons, characters, specials skills, dash and others) especially since the bosses are extremely hard to beat ! At least it’s very permissive, when you die you don’t lose your money or anything and a lot of save and teleports…
But if you are experienced and love metroidvania go for it ! The boss are really difficult but always rewarding with a new skills, a lot of hidden things in the wall and the game itself is just beautiful. The map isn’t my favourite…not so easy to read and the legend is hard to understand but overall very good game !
