Round when it shoots thousands of bullets in crossing waves, stay on the right hand side and fit into one of the gaps as far right as you can manage. These gaps start off pretty big and only get a little tight as they move left. On the wave where it shoots a smaller number of bullets in short waves, followed by a wave of larger bullets, quicky dart through the wave of small bullet and hide in the gap between spikes (where the bullets fire from) and all the larger bullets should miss you. For the missiles, stay in one bottom corner to lure the missiles that way, and slowly move along the bottom of the screen. The 2nd wave should launch as you're about halfway along the bottom. Then, quickly dash the rest of the way and up, around the 2nd wave, and very quicky go all the way back across the screen, above the second wave, and drop back down to where you started before the 3rd wave launches, and repeat. haven't figured out a strategy for the rapid laser pulses.
'Complete 15 levels without taking damage. best so far: 14'. I have to assume this is a typo, there's no way ApprenticeChief could think anyone can beat the last boss without taking damage.
Enemy accuracy needs to be fixed. Enemies in the distance are just as accurate as enemies 3 feet from you, and it does matter if they're standing in the open or just put their arm around the corner and started firing wildly. They have the same accuracy, which makes no sense and is unfair, and they're harder to hit and can get you in one shot. It makes the cover/building-windows section in the last level ridiculous. Also annoying in the Hostile Arena challenge, when enemies on the far wall poke their arm around a corner and get you on their first shot.
why do prices seem to fluctuate so much? Fabric was $80 on the first island and $60 on the lighthouse island, so I bought 8 units on lighthouse island and shipped it over to the first, and now it was suddenly $50 per unit.
