Fun concept. Love having to use puzzles to defeat the bosses, it took me a while to figure out how to deal with the spider, I thought the idea was to use spin the station to make the bosses fall to the spikes but the spider is climbing the walls of the station, then I figured out I had to push the big red button to electrify the pads to deal damage, maybe you could have that button have like a flicker glow, that would make it pop and catch the player's attention.
The bosses are neat, pretty easy to deal with as the main focus is to figure out how to kill 'em, I personally think the first boss is the harder of the three bosses, the hornet I just had to wait till the falling barrels and let gravity do the work for me and the spider it was just the waiting game until it got to the pad and dodging projectiles, I barely even spun the station on that one.
Overall, pretty fun game with neat puzzles.
