''Clyde's Adventure'' is a platform computer game released by Moonlite Software in 1992. The objective of the game is to explore castles, collect gems, and find the exit. Clyde, the main character, has a supply of energy that depletes whenever he walks, jumps, or falls from a great height. If his energy reaches 0, it causes Clyde to die with a shriek. With no "enemies," ''Clyde's Adventure'' is predominantly a puzzle game. The challenge comes from avoiding traps, using Clyde's magic wand to manipulate the environment, and finding the most efficient route before Clyde runs out of energy.

The game has two chapters, each containing 16 castles:

* Episode 1: Lost Treasure of Tahookaboo
* Episode 2: The Vanished King

Originally, Episode 1 was shareware, while Episode 2 was available only upon registration. Moonlite software has since released the entire game as freeware.

''VideoGame/ClydesRevenge'' is a sequel to this game.

!!This VideoGame contains examples of:
* EpisodicGame: There are two episodes making up this game.
* FrictionlessIce: Clyde will slide at a constant speed on ice, even if he lands on it directly from above. He can freely change his direction while on it, though.
* GottaCatchThemAll: You must find all the gems in each castle.
* HintSystem: There are notes on the walls that provide often vague hints, funny statements, or [[TrollingCreator mock you for trapping yourself]] (see TrialAndErrorGameplay below).
* MacGuffin: You find a treasure in each castle. They serve no purpose beyond that.
* PixelHunt: Much of the time you have to locate triggers for the appearing/disappearing walls/floors mentioned below or hidden teleporters (and [[TrialAndErrorGameplay hope they're in your favor]]). The HintSystem helps a little.
* TrialAndErrorGameplay: A central mechanic. Mostly in the form of walls and floors that materialize out of or disappear into thin air, called "magic" by the HintSystem. A wall might suddenly [[UnwinnableByDesign appear behind Clyde in a dead end]] or disappear in front of him, sometimes both. A platform might appear [[LeapOfFaith as Clyde jumps]] or disappear under his feet, which might send him into the intended path or SpikesOfDoom. Some teleporters send Clyde into inescapable rooms as well.
* WizardNeedsFoodBadly: Clyde has an [[LifeMeter Energy Meter]] that depletes ''very'' fast as he walks, jumps, and [[FallingDamage falls]] (and touches SpikesOfDoom in later levels). He needs to collect dots of energy to replenish it.
