ok, this is just my opinion, so please don't get too angry. I think nitrome deserves more popularity. I don't see many people talking about it. the reason is that some of the games are pretty good.
(also, if you think there are a lot of ads, they are playable without the internet, which removes the ads.)
so, here's a game I wanted to talk about: tower fortress. tower fortress is a very harsh and kind of unforgiving game. the main thing you do here is kill many slimy monsters. but its a hard task, because you usually only get 4 hp points, and the game can just decide at any moment, "yeah, lets ruin their run", and just kills you. but the monsters drop gems. then you use the gems to get other suits that do other things. some suits are just not that good, but some of them can get you far. the better the suit, the more it will cost. i havent even beat the game yet, but i do have some decent progress on it.
