Here are the first sketches of my platformer, do you think there are chances for success?
WRS First off.. you'd probably need to and be able to translate to English sometime.
The graphics of the environment look promising. Did you create it all yourself?
I don't like how the player moves sideways. Should be way more fluently and more body parts moving. But maybe you're working on that. Also I didn't recognize it as a Rabbit in armor at first.
You will definitely need an angle for this platformer. Currently it looks like one of those 'dime a dozen' platformers with nothing special about it. You will need to make it unique if you want it to stand out.
Also define 'success'. It looks like you intend to release it on mobile. But as an app on the store, sell the game, or..?
Hope I wasn't too harsh.
