Considering how short the game is, upgrades are far too expensive. I also like to nitpick that the background objects can be hard to differentiate from the ones that you can hit. You've got an idea going, it just needs some polishing.
I like this. It isn't a shot by shot walkthrough, but a HELPFUL strategy for if you get stuck. It really saves the headache of being stuck on a level and never wanting to play the game again...
Major glitch. I hit a high level my health goes negative. and then I die after my first move on floor 148. I am lead to believe anyone of a higher level is a hacker.
