Sure thing you made it with some effort, but WTF, with this graphics? 20$? God, please. For 20$ you have Dead Cells, The Binding of Isaac, NOITA or Neon Abyss. It's not a metter of comparing genres, I know. It's metter of good graphics, interesting mechanics, price and balance of all those things. I can't see this balance here. You will see this in sales. Just sayin'...

I like games like this (Supaplex, Crystal Mines), but the price mate!
