Love city builders and merger games and this is a fun frantic spin on those genres.. A couple frustration points: trying to move objects hidden behind buildings is a bit annoying (can be solved by scrolling out but then it's harder to distinguish what type of buildings they are. Also, buildings naturally upgrading can sometimes annoy, because it feels bad to be setting up for a big merge then one of the things you were about to merge into suddenly upgrades, throwing the plan into disarray.. Maybe that was the point. Extremely enjoyable!
