It got laggy at points but it handled pretty well compared to other games, one problem I did have was sometimes my collectors would just freeze and do nothing... but I would just buy some more.
Same thing happened to me but by zooming all the way and not letting all your bots in your view it sped up alot. Remember that im doing this on a School Chromebook.
Thanks for the feedback on performance. There is a very large engine update coming for the development software I am using to make this that should speed up how the game performs significantly!
I think im the only one who gets positive figures.
