Brick^2 (Brick by Brick) Prototype

WASD to move, mouse to look, Ctrl to crouch, Shift to sprint. Press escape and the game should give back control of your cursor.
Note:
1-It takes around 20-30 seconds to load, so don't be alarmed if it doesn't instantly start.
2-You WILL NEED TO CLICK ON THE GAME WHEN IT STARTS to prevent your mouse from escaping.
3-It is possible to reach every white platform in this prototype, it is not easy at first. My advice is to bhop or sprint before you jump onto a slope. Referring this video may also help.

This is a unity scene I have been using for prototyping most of my learning in unity.  This is essentially my 'first' actual unity project developed entirely by me. (My first time working in unity was 2 weeks ago at time of writing, using the standard Unity FPS Tutorial module). This project was a learning process involving textures, cameras, scripting, modeling, inputs, play controlling, player movement, and more. Overall I see this as an "exploration of design concepts brought about while learning unity" since I hesitate to call it a full prototype.

Any form of advice or critique is greatly appreciated, and heavily encouraged!
