I see that this game resembles Super Meat Boy, and I think one key thing to focus on when you are inspired by another game is the mechanic of the game instead of the visuals.
The two points can be summarized as "Feeling" like another game, is much better than "looking" like another game.
I can think of two reasons to focus on mechanic instead of visuals when working off of an inspiration:
- The mechanic is what actually makes the game fun. The visuals are important, but what made Super Meat Boy a fun game was its mechanic. So in this case, super tight jumps and controls resonate with players more
- I think people will see the visuals of something they are familiar with, and then be greatly disappointed when the mechanics are not what they expected.
I hope you consider my advice, and please don't take it personally -- I just want to help!
