Nice start, but as others have pointed out the scrolling makes this rather difficult to play, especially on a laptop with solely a mousepad. Your layout is very vertical, and a lot of your elements would be better placed inline (horizontally). For example, the purchase buttons can be horizontal to the name of the item being purchased. The padding of the resource rows can be reduced by 2 pixels as well. A small shave can really make a large difference. Finally while you are working on the layout I suggest adding your own splash of color - this game visually looks no different than the other Bootstrap idle games out there.
There are graphics options in the More Tab if you would like to customise the look. There are options to change the theme and colour scheme, as well as compress the resource rows. However, I will take your suggestions into account for future design changes
I've noticed a steady progression in quality in your games. There are still issues with pacing, but otherwise I am very happy to see the progress you have made. Keep up the good work.
I'd definitely love to see this game expand just a bit more, even if it is in a sequel or expansion update. The tradeoffs between working, training, and resting is an interesting concept, and a lot can be done with that kind of system.
