It's pretty alright!
I liked the gameplay mechanics. Although the concept of riding/driving down a straight road, while avoiding incoming obstacles such as other vehicles or walls, isn't particularly new, it has been implemented well here. The controls are solid, the game is easy enough to understand, and overall, it's fun to play, and works great as an arcade game! Also, the need to conserve your stamina, while watching your surroundings and your current speed, makes this game a bit more challenging, which is also a plus!
The graphics are okay, although, I didn't really enjoy sound effects, or rather, how they are sounding. While on their own, sound effects and musics are alright, their stereo pan, isn't well thought out. The intro music only plays in the left channel, and the stereo pan for the sounds in the actual game, was unnecessary in my opinion.
I must admit though, that the theme of this game, as well as it's correlation to the jam's theme, was very interesting and unique! I mean, you need to be one creative mind, in order to base your game on leap years, and therefore create a game about time traveling via riding on a bike.
As I said, it's a pretty alright game. It is fun to play, the graphics aren't bad, and the way the theme was interpreted, was pretty clever!
