I tried your game, and here's some feedback:
I like the concept of this game and graphics are probably better than in any of your older games.
This game could be pretty good, but currently it's just too simple and way too repetitive to actually make one want to play it
more after a few tries.
Also, what's with the prices of the things in the store? The cheapest item costs 1000 wrenches? I currently have about 60.
Acquiring enough money to buy even one of the items would take years, and with the gameplay being currently very repetitive and mostly
consisting of spamming the directional buttons, there is no way anyone is going to get enough wrenches for even the cheapest item.
You have to be a bit more realistic when you set prices to items in your games' stores. The cheapest items should be something one can buy after a few plays.
You could take at least one 0 away from all of the prices.
I also agree with all the suggestions jonathang gave to you.
This game has potential, as you've already done good work on the menus and the graphics and now all you have to do is to make
the gameplay more interesting. I hope you will keep working on this game long enough to make it as good as it can be.

Oh, I have a question, too, how do I gain access to the other levels?
