This game is fun. It took me about 10 minutes to unlock the duplicator. Things were going smoothly until I messed up the wood block placement and the sand no longer flowed into the conveyor. and had to try again, as I couldn't delete blocks. The game only runs if it's the tab I'm on. I should've realized that sooner. Because the collector could only collect 3 tiles, width, I could only make so many duplicators until it overflowed. I had reached the maximum sand it could collect. What's more, is that I messed up my placement, so it would be harder to place crushers because I've already shaped my wood in the shape of a vase. It's been a little over an hour, and I only have 10,000 sand. I'll need 75,000 to get a crusher.
I really like this game. I know this is all concept, and all of the problems above would be fixed when the features come out. I'm Just tired. I'll be looking forward to this game if the developer continues with it.
