Ditto what others said about reduced functionality/overly complex controls and also on the colors. There does need to be more contrast. Please also add a counter XX/XX bombs flagged. I was certain I had finished a level, but didn't get a win screen. I saw no empty spaces and didn't find any mistakes. Color + counter would have helped solve this issue. Another note on color - the yellow background has GOT to go.
It's nearly impossible to execute precision stacking when the spaces leftover won't let another piece in because of ears! The T is nearly impossible to work with as it NEEDS an open gap to sit in or otherwise be balanced out almost immediately, which is rarely possible due to oversaturation of dedicated placements, a near-instant gravity effect combined with very slow drop of next piece, and NO PREVIEW OF PIECES TO COME.This leaves you either always building your tower to accommodate a T piece or building directly over its center of mass forever afterward. Not fun.
...That'll teach me to comment before reaching the next screen. Way to try and look smart for knowing the reference when literally everybody was told immediately afterward exactly what the reference was, chibis223. -facepalm-
'SAVE' -- "Neural net saved." -- Refresh. -- Hardware arrangement not used since this morning, tons of upgrades missing, and much research to be redone.
I'd REALLY love to be able to replace blocks instead of having to tear down everything in the column. It would be cool to see other types of buildings like schools. You could also expand the game by using research to study rocket science and educating the populace to become employees, then sending them off to other planets.
