Well put together game overall, nice music, great pixel art, decent gameplay. Although I have a few problems. First off, you need to make better instructions to the game, like how do you earn the points for upgrades? Second, coins do almost nothing, the concept of items is weak. One use items that cost that much is a waste. I ended up selling every item I picked up, just to get the gold achievements. Altogether it's a good game, but it needs some tweaking for sure.
