Bike: Class Begins at 9

Controls:

Press "Space" to begin the game.
按空格开始游戏

Press "Space" to switch cameras.
按空格键切视角

Press "R" to respawn from last checkpoint
按R键主动重生

Mash "Q" and "E" to pedel. 
QE交替连按来蹬踏板

Use “←” and “→” to turn. 
左右方向键转向

Friendly Suggestion, you really need to mash them fast on uphills and startups, but flat ground shouldn't need too much mashing, so don't wear yourself out before climbing.
小小的提示，虽然上坡和出发的时候要快速连按，不过在平坦路段上骑行时别按得太急，你的力气（字面意义上的）得省着点用

Avoid Cars and building as they instantly kills you.
墙和车会秒杀你，别碰

Description:

        This is a game where you have to ride your bike to school and not be late. What sounds like a simple task might be a compressed experience of an hour of desperate pedaling to drag your (my) 250-pound fat ass uphill, with a time limit. I picked the topic both for the sake of absurd humor, and memories I've had for my high school days. 
        My favorite moment in developing this game is definitely the development of bike physics. To simulate the pedaling, I decided to actually use the back wheel to send my bike forward physically. Which resulted in the fact that I can't lock any dimension of my Rigidbody. And deciding to use physics caused a chain of technical bottle-necks.  And guess what's my solution after a bunch of failed coding? MORE PHYSICS. I actually opened up "Besiege" (a physics sandbox game about building machinery), and made models which eventually led me to my solutions. My "bike" ended up  as a Merry-go-around with a bunch of invisible hinges. On top of the "pole" of my "Merry-go-around" lies a spring joint which can adjust its attraction to allowed the bike to "roll" naturally and stay upright when moving foward. I also originally wanted to make the NPC cars move according to logic and animator but I ended up simply making them mini 4WDs, like the toys I used to play. They literally have no ai and their movements are all guided by invisible tracks (They even has those guiding wheels like 4WDs do except they are invisible.) The making of this game ended up as a crazy lego building experience which is the most hilarious because these absurd "machines" looks totally different than what they actually are.
