I Have A Mouth, And I Must Scream
A downloadable game for Windows, macOS, and Linux
This game was made for the Global Game Jam 2017. (Original page here.)
You are an alien trying to escape Area 51 in the middle of a power outage, avoiding other aliens on the loose that want to eat you! Luckily, your species is able to see in the dark thanks to echolocation!
Unfortunately, the only way your species can produce sound waves is by screaming ridiculously loud. Not very stealthy, but you'll have to do the best you can not to attract the attention of the other creatures, and make your way to freedom!
