Ok Wow! Thanks all, I'm thrilled people are loving it!
It was as fun to make as it is to play!
here's a few tips that will help beat this basterd:
-the bomb glitch (press pause while bombing a boss for 30 sec) def works!(on some bosses)
-avoid water in the tank until you get the dive mod
-once you get hover always try to keep the gauge full!
-If you get lost remember to GO UP!
-To beat the bubble spitting crab keep your GUN gauge full!
-in the tank segment you can farm P (health) and 1 (hover)
-You can regen your "on foot" health by jumping back into the tank
