Hm.
From a purely technical perspective, it's good (the controls work, it has a goal, etc.). However to actually be a game that's appealing, it has to either be entirely original, or at least have something original to offer that no other game does.
Remember - as long as your game is good from a technical standpoint, and doesn't glitch up, it's a GOOD GAME if it has a new aspect that no other game does. That's why this game isn't actually a good game. When you try again, try:
-graphics (judging from this game, graphics is sort of your weakness
-gameplay twist - do something no other game has
-totally new idea - all types of games need to have been thought up by SOMEone!
good luck! And remember, this isnt a BAD game - it's just not new!
