FireBeast Studio is one of the more productive game studios. Most recently they have produced smash hits such as Zombo Buster and Might Knight. Mighty Knight is a battle game in which you help a brave (& mighty!) knight to defeat monsters.
FireBeast seems to get (almost) everything right, from stunning graphics (see image below) to engaging gameplay. The games also feature a little bit of humor.

Mighty Knight will keep you entertained for a while. The walkthrough already takes about 54 minutes. But, hey, it’s summer holidays. So you have enough time!
