the gaming idea is superb: easy to learn, hard to master. you only need the arrow keys. there are some things i'd like to mention though.

- the scene is a bit overlit, on my laptop, everything seems white-in-white.
- the bulldozer model sticks out, its style doesn't match
- joozey's "flip me" button
- no skycube
- movement: press forward and left or right. it feels awkward.
- camera should follow the mouse without having to press rmb

if you want to extend the idea,
- add a tutorial
- better bulldozer model

i'd also like to propose something to you. please check you PMs.
