Hey iceangel ! First time i see you posting a game here ! I know you are a great forum-poster
I think that you game is a good proof that you know how Construct2 works, you master it pretty well. Now you will have to work on everything that is not directly part of the game development.
I mean polishing graphics (for now, they are ok, but we don't feel obstacles are part of the road, for example)
And improve the "game feel" because after some minutes, we master the game and can't get more fun with it.
It's not an easy way, it's long, you need to study your favorite games to see how game developers have done it (why this level is like that, why the textures are like that, why the monsters look like that, why the music here is like that, why EVERYTHING is here, what is the reason ?) and it's not sure that you'll get it for your next game.
But they are good questions to think about, for any games.
