Review of Monster Boy & Cursed Kingdom Steam Demo:

Controlls are fluid, music is lovely, bit on the lauder side. I played this title with the controller & I was surprised how good demo is. Not to easy, but not unbeatable by me. I could run it perfectly, enemies & content in the demo were varied, wonderful and I saw lots of content. I died once I think, but I will definitely buy the full game. Devs promised slightly lower than 40$ price and I think 30$ would be realistic price value wise. World is wonderfully colorful.

I also think this is very similar to Wonder Boy to the T, but care not, really.
