Let's ride!
The particle effects are off the chain! I had fun with this.
I think the only thing I'd change is some kind of distinct/more-urgent "you got hit" sound effect: I was frequently focused on all of the things coming from the right hand side of the screen that I wouldn't monitor my health.
The graphics are great. The wheelie effect is fun. The 'rides-off-into-the-sunset' animation at the end is satifying.
Good work, as always!
