I really like the game and I'm looking forward to the next versions with new content! But it seems to me that something stands out a little from the general process where the player does most of the actions manually - upgrades of radar, sensor, modules, etc. which are currently just bought for points in a separate menu. It might be more interesting if hardware upgrades could be bought in a store and installed on their own. For example, at the beginning of the game, give the player only a few servers, and he must buy the rest in the store and connect them himself in the server room. Or change the boards in the radar, connect solar panels to the ATV, and so on.
