it not good..
i mean.. the smileys are all the same.. you can maybe make zome other faces on different smiles and even make some bigger then others, or make some faster then others... also the character doesn't look nice, you could easily make a nicer character.. the game is also too easy to survive.. you could also easily add some extra difficults in the game.. and even add some new levels. and if i push the right mouse button the character disappears so this is cheat that everybody could use.. and it also says that i have 3 lives but when i die it just says 'game over', so it doesn't looks like there are lives. also I'd like to know what the clock is for in the corner? and the background is just a bad- drawed drawing. but i do like the sound and the engine is also kinda lol, but only if you improve everything..
so i give you a 3 for all your effort, and you could be happy with that.
