After the basics of robot control, it is time to introduce a upgrades system as these are a core part of the game. From the beginning I try to make the system as versatile as possible in order to be able to add various kinds of improvements in the future without having to interfere with the system core. So far I have only devoted to programming, which is surprisingly a lot in the background, the visual aspect is still waiting for its time.
In future i want to have picture of particular upgrade, description and some category related parameters, like strenght, speed, fuel efficiency for drill

Things that i done:
- added 2 classes of upgrades (Tank and Drill)

- create upgrades category system and creation of individual upgrades

- basic working UI that react to clicking buttons (done all with scripts, no manual work needed)
