Awesome, perfect!
This game was great. Music was superb. Controls are minimal and precise, which keeps things simple, but allows for good map design. Pacing was incredible, action was great, variance was great. I had a lot of fun. Looking forward to future releases. I was disappointed in a few of the guns; they seemed worthless (saw blade, infection gun, and machine gun).
It took me ~2.5-3 hours to get all of the achievements. The final one was a real bitch, ahaha, but damn, I'm glad you made it beatable! I had to play that final worm level like 50 to 100 times before I beat it (~3 tries with the acid walk boots).
For anyone playing this: make sure you don't buy too much junk (the only weapons you need are spread, laser, and rocket). You need $6,000 for the final item/related achievement (which basically gives you all equipment; you'll see), and you only get money from the coins and website visit promo machine.
Buying guide:
Only get 1 of each permanent sphere. Only buy like two pieces of equipment of each type before getting maxed stats. For special attribute equipment, get the no loss of speed when damaged armor, the no speed loss on goo boots, and the save 1 sphere of each type if you die gloves. Also get the acid boots, as they will let you complete all of the levels in a few tries so that you can get the final item, then go back and beat the ones you used them on (MAKE NOTE OF WHICH LEVELS YOU BEAT WITH ACID BOOTS IF YOU WANT THE FINAL ACHIEVEMENT).
