Anyone know where the music for this can be found?

Read the tutorial and understood how to play the game, seeing as it's relatively simple and straightforward. But when you're in a level it is very hard to see the enemies because they're off the screen until you're on top of them. Then comes the upgrade screens which are very overwhelming and confusing partially due to the fact that it's hard to tell the difference between buttons and elements that highlight when you mouse over them. The game finally lost me when I couldn't figure out how to equip my skill I unlocked, I realized I wasn't interested in playing a game with mediocre and confusing gameplay.

Wonderful piece of work, but I am seeing that full-screen-quit bug where I can't log out and it eat 8% of of my cash when I reload.

Step 1. Find a Carbine
Step 2. Find a stronger/better Carbine to replace it
Step 3. Find a similarly strong/good Carbine and fusion both Carbines
Step 4. Find the best Carbine attachments and put on the new Carbine
Step 5. Repeat Step 2 to Step 4 several times
Step 6: ???
Step 7: PROFIT!!!
