Great game but it does not see to handle "Speed up grid" very well, and when zoomed outv to the A, B, C etc, grid, it is not possible to buy the speed upgrades, batch even though there is currency. In all other means, this game has potential!!
I found out that I had a block of code commented out for the speed up thing, should be fixed now (I think), there's a few quirks I need to work out how to fix for the max zoomed out view but thanks for your feedback!
