Needs a lot of work!
It can be one of the greatest games EVER! But you need to improve it a lot.
Personally I tink you need to make the amount of creatable land limited in some way so that it's hard to beat levels. Add more challenging levels. Fix some glitches. Make a real character! And have him be a hero that can create ground beneath him.
Ok. You don't need to do all that. But when you do I know I'll have no choice but to vote 5!
For this I know you put a lot of hard work into it already so i give it a
2/5
Good luck in the future!
Great start!
