Okay, this is what I could gather from playing for some time. This game isn't hopeless, it's got potential. A few things could be improved, if this game were to be revamped with a lot of changes, I would probably like it. So, for feedback, the sounds definitely need to be changed, and the art refined. This game could definitely make it with a few extra options. Also as you said, about holding off until you have more experience, you could definitely revamp this, since it's not a bad game. And for ideas, maybe adding a shielding system would be a good idea, since it gets kinda difficult to stay alive after a few waves.
