@setsuai_kijo Such a tooltip would be useful for colourblind people too, as well as for those of us who change the colour balance of our screens in the evenings (so as to not disrupt melatonin production too much).
Currently doing the "reach 350 Generator III" challenge, and have 339 right now. The remaining 11 will probably take me about a week, even with some active effort.
Never mind the wind way above the Karman line; what the hell are planes and airships doing at an altitude of more than 200 km? How are they even flying in the extremely tenuous atmosphere?
Out of curiosity: how is there wind at 440k feet? The Karman line (100km or 328k') is the altitude at which an aircraft would have to fly at orbital speed in order to get sufficient lift.
Topaz Kicker tends to stay around after her target orbs have been matched, keeping other allies from appearing. I have to refresh the page to make her go away.
In story 2, Thor the Builder tends to get stuck after his targets have been popped, and the only way I've found to make him leave is to refresh the page.
In agreement with phynnboi's suggestion: Could you change the graphics slightly, so that it's easier to distinguish between unshaded squares that should be shaded and shaded squares that should be unshaded? As it is now, those are too similar.
An improvement I would like: if the arrows rotated so that they always indicated the piece's plane of gravity. Another option could be to colour-code the planes of gravity.
The fourth problem makes no sense. As far as I can tell, it's a multiplication problem, and if x=5, then if x*x*y=5, y=5, which is inconsistent with x*y*y=4.
