I love the Lost Viking game back in the 90's. I guess it was part of your inspiration for this amazing game. Lots of levels (I HATE THE SPIKES!!!). The music is perfect. Great use of the theme and how the complement each other.
My only complain is about the control... and the "oil feet". I fall sooo many times by just tapping the right key to slightly move just a bit. But the rest is just perfect.
Amazing game! Congratulations!
BTW: I love the Mario reference in the secret level, detect it on the first platform. And the ending with the stair... love it!
Please check mine if you have time. Thanks!
