In Spider, the player has to swing around using webs spun by the little creature to collect fireflies. One can't help but be reminded of String Theory, though Dillon's work has controls suited for fast-paced gameplay.

Left or right click to shoot webs, and hold the buttons hang on for dear life. Press space to tighten your webs and swing.

Differentiating webs can be a tad difficult at times, and the application doesn't handle task switching too well but nitpicks aside this is definitely worth a go. Four levels only.
