I like it; it's quite fun, although there's a couple of problems.
First, and mainly – the game does not restart when you lose (making 'highscore' pointless). Whether you crash the car or run out of fuel, the game does not restart. Now, I later found out you can restart the game with 'R', but it's not written anywhere. You shouldn't rely on people's ability to 'guess' the controls. What about a restart button on the screen when it's Game Over?
When you crash, you can also potentially get hit twice immediately afterwards (e.g. when hitting a wall). There should be some temporary invincibility.
I also did not see a single powerup until the 20k checkpoint (or weirdly, after I died). If you stand still and wait, some do appear,
I was quite thrilled to see a "boss battle", but I can't get past it. The car becomes invincible, drives in random directions (no matter which keys I press), bounces and you're also no longer colliding with items like spikes or powerups. I'm not sure what you're supposed to be doing (high score: 20,003).
And AGAIN, I later figured it out – the boss which looks exactly the same as your car (!) spawned and killed me before I noticed. I thought I was healed before the boss battle, instead, it spawned while I was close to the centre and "replaced" me.
But I think the checkpoint and especially the zoom out is a good idea. I'd at least make the enemy car blue to make a distinction.
As for other things:
– I'm not sure if 'Boost' is useful. It just makes you more likely to crash.
– Not sure what the "crowned bean" powerup does.
– The boss probably should get hit by spikes. Also, I feel your fuel runs out too quickly during this phase. You have to evade his attacks, but doing so makes you lose when you run out of fuel.
– Why do we need the compass? Surely we can tell which way the car is headed even without it…
– The whole page scrolls when pressing arrow keys, especially when you have the compass powerup. Try the workaround as described here:
