I finally actually managed to beat the game I am highest scoring player in the world (according to steam at least 😛 ). I used my keeper for a whole game he was my only fighting unit in the game and as fun as it was to win I had an issue with it. I got lucky to find some gnomes killed then and easily leveled off my guy out of the bat to level 8-9 is. After that I killed few bandits and got raided by dwarfs which I demolished with my bow without them being able to even touch me.
That was done within first 30 min of the game. After that nothing on the map was the challenge anymore and game was basically me running around and killing village after village. I just by myself took down the dragons, entire knights castle without even breaking a sweat. Difference between keeper level 5 and keeper level 15 is huge. I think game is a lot of fun but should have some sort of balance or cap on the levels for creatures because super soldier program is very easy to achieve
