Last night, I played Day of the Tentacle again and was reminded of how funny it is. The game is set in a point-and-click universe with Hoagie, Bernard, and Laverne, where a tentacle tries to take over the world. If you enjoy puzzle-based point-and-click adventures, I highly recommend playing it!
The game's biggest highlight is the amount of things you can discover - it's a truly immersive experience.
Also, on a side note, if you're a fan of Star Wars, you can call 1-800-STARWARS for a fun surprise!
