Tips from the 77 Crowd
- If the game stutters, blame your other tabs first; close the video-heavy ones and HTML5 runs clean on any Chromebook.
- Short daily sessions build skill faster than one marathon; the muscle memory does its work between plays.
- Treat your first run as a scouting mission: find out what ends the run before you worry about the score.

Can I play Alien Quarantine at school?
