404Sight is a parkour platform runner made by graduate students at the University of Utah to show support of net neutrality.
It's a short game, but it does what it sets out to do very well. The game is mostly fast-paced, but there are some points (particularly towards the end) where you have to stop and make sure you're going the right way. Many levels feature alternate routes and shortcuts, allowing you to replay the game in hopes of a faster time. In addition, the levels load seamlessly so you can just keep going!
You can play with keyboard & mouse or a controller - I found KBM to be easier to handle, but that might just be personal preference. Either way, the controls were responsive and easy to understand.
The game has several cool mechanics that I found interesting. You have "ping" which you can toggle that allows you to see and use/avoid important features (like fast lanes, slow lanes, and the purple jump things). You can often leave ping on, but crossing slow lanes or inhibitors (red areas) while active slows you down and can kill you because your speed and health are essentially the same thing. If you have enough speed, you can also use a dash-type move (like something from Sonic the Hedgehog) to destroy inhibitors.
The visual style of 404Sight is quite cool with lots of bright neon lines everywhere contrasting over an otherwise monocolor cityscape. It reminded me heavily of Tron, and that's a plus in my book.
