I'll bite and try to give you a useful review.
The game itself is actually good, the mechanics work well, and the gameplay is good with the upgrade system engaging the player to play for longer than a minute. Of course, you should always try to improve yourself, if you want to make games, and who knows, maybe someday become a pro. The worst and most difficult part in making a game, which is coding, and making the game working, is not a problem, since you already proved that you are capable of that. But what this game obviously needs are good graphics and slightly better sound.
Apparently, you are "no budget games", but the beauty of newgrounds is that you don't need budget, you just need to find someone who can work with you. Search for someone who is good at pixel art (pixel art is an instant 5/5 always, every time), ask that person to create some graphics for your game, then search for someone who is good at making video game songs (there is a whole genre here dedicated only to that), and voila, a good game is made. And of course, don't forget about giving credit when credit is due.
Obviously, I assume that you made this game "just because", but you never know when it stops being a hobby, and becomes a lucrative job. It's much better to start with one good game being a hit, than making thousand meh games.
And that's it from me. Now, I'm going to get drunk, because it's weekend.
