The game was fun but i think it was too easy (other people might think it's not but for me it was.) and i think that hard achievement should have like you have to play all lvl without getting hit or something. atleast in 10 lvls not bonus well that would make it harded but yeah.
I dont know if im just blind but it would be nice if there would be a exp bar so i would know how much to lvl up. :D (although if it's on purpose so farming is more "harder" or something i kinda get it.)
i think this is a great game but, if this would go on steam i think it need more lvls, upragades, monsters and maybe little bit more challenge but anyways good luck on steam greenlit. hope you make it and do these kinda upragades on your game!
