First, this game is very fun^^ I would like to suggest some features
- We should have predefined building template as map-editor e.g. player have 10 slots to layout buildings/conveyors. If grid/tile's limitation is required 30x30 grids should be enough. When you're playing and select the menu, you see those slot (maybe just a number 1 to 10 images with user-defined name), click it and voila. *building resource're spend accordingly
- I think Overdrive Projector is interesting but it seem we spend the resource and unexpectedly power used (even more than percent improved). It would be interesting if it not cost more power as it already have it power used and we must tackle its layout position already. Providing enough resource speed to that location is also hard enough.
