Good game with familiar mechanics of many platformers.
I saw only 3 enemies and 1 boss so far but how they drawn is surely ok to me.
Animations done pretty good, although they aren't very soft and sometimes I see frames, but all in all I'm excited to see the full game.
P.S. if you're interested in help I can translate the game or maybe give you a few ideas I have in mind. If not, continue to do what you do.
