I decided to have a look at HTML5 Canvases recently, it turns out they are pretty fun to work with, so I managed to make a small game with one.
The game is called Circle World, and the objective is to collect the green circles while avoiding the red circles. My nieces and nephews had a lot of fun playing it, which is good as it took about half a day to make.
Just a few details on the game:
You can control the yellow circle with WASD, arrow keys, or click to make it chase the mouse.
After 15 levels the red circles will start to move, and will increase speed every 4 levels after.
Circles will peek through the boundaries on the opposite sides.
