Hey man : D

I assume you're tight on money since the visuals are pretty much MS Paint quality?
I can understand if so. However, you need to add sound-effects.
For that, you can use Splice. You pay a low monthly fee and can download
hundreds of great royalty-free sound effects.

The gameplay and presentation is neat. Nothing unique or groundbreaking but
well done imo. As for the visuals, if you actually CAN afford to hire artists,
then you can make a thread on Deviantart's Job Offers forum. I have hired all my artists there and it's wonderful. Most there deliver professional commercial quality,
and various artists have various price range. Some might even suit your budgetary limits.

Good music, I like it : D one suggestion is, if not offering the player a volume setting,
reduce the music volume in the game engine and make voices (if hiring actors)
and sound-effects louder and more in focus.

Best of luck man and you can keep in touch with me here via messages if you like
