Hey, that was fun. Some of the pacing was a bit off if you wanted to turn this into a full length game. I think giving the player 7 buildings to make at once can be a bit overwhelming in the first minutes. It might be neat to have a different things to build as you go on. Maybe give the player options to build roads between places to increase drop off speeds. Also, more visual changes when you upgrade things, I noticed the rocket did but the buildings would be nice as well. Some of the text on the rocket is a bit bunched up and hard to read. Maybe giving the text a box around it could help. The clarity between the ground and buildings could be better. Maybe just lowering the brightness of the ground could make the buildings pop more.
This last bit, not saying you do anything with it, but i'd argue your game is actually a base/city building game, not an incremental game. I'm just being pedantic here, I just wanted to point it out. Cool entry
