Very polished point-and-click game! I really appreciate the effort you put into writing unique lines for different item interactions.
Gameplay-wise, the game is solid, but I felt that some item combinations were a little far-fetched and hard to figure out—like using the calculator on the wand or using the plant to power up the laser gun.
Another small issue is the door placement. When entering a room from the hallway, the door to the inner room is on the same side as the hallway entrance, which made it feel like it was the door I came through, not a new door to another room. That caused me to get stuck for a while.
I also found a small bug: when you use the wand on the dog to turn it into a wizard, then leave the room, it turns back into a dog and you're stuck. I eventually managed to hit the dog and died, so I wouldn't have to restart the game.
All of these are minor issues—the game is still amazing and really fun to play. Great job!
