This example demostrates a way to put things together and create a simple platformer game with a Gopher!

Use arrow keys to run and jump around. Press ENTER to restart. (And hush, hush, secret. Press TAB for slo-mo!)

The retro feel is, other than from the pixel art spritesheet, achieved by using a 160x120px large off-screen canvas, drawing everything to it and then stretching it to fit the window.

The Gopher spritesheet comes from excellent Egon Elbre.
