Hey great job with this! I liked the sound changing as you jump/move, although it was a little repetitive after awhile. Cool mechanic with self destruct for extra platforms, the only thing I would say is be careful using CTRL as a keybind for HTML5 games, CTRL+D bookmarks the page, CTRL+W closes the window, which I found out the hard way. CTRL+A selects the whole page, and CTRL+S tries to save the page, so WASD + CTRL not fun for browser game.
