I didn`t had a particularly innovative idea for the theme, and build a sidescroll shooter I called “Infinite Loop” that is focusing on a simple risk vs reward mechanic.

“Infinite Loop” – A Steam Punk Sidescroll Shooter

At the start you have 10 seconds to live, and you need to collect orbs to gain more time. But you can´t have more than 10 seconds to live at one point. While you are shooting enemies to increase your score, you always need to keep an eye on your remaining time.

There is one power up which enables you to temporarily deal more damage and a high-score list that shows the 5 highest scores at the end.

You can give it a try here: Play Infinite Loop
