It was a bit too good.
Gameplay: Because Chex Quest is child friendly it has a million plotholes. You have guns - I mean zorchers, that shoot zorch. You have to shoot zorch at flemoids to send them back to their dimension, otherwise killing them. The gameplay is identical to Doom, so please, read my Doom review.
Graphics: Chex Quest's graphics are Doom engine graphics, so expect it to look good, especially if you have an open GL source port. The game runs great, just like Doom, except all the graphics have been rewritten for children.
Sound: The music is great, but if you want to here some truly epic music, play chhex quest 3. All the sounds have been rewritten for kids as well.
Story: A Galactic Federation of Cereals planet has been assaulted by flemoids from another dimension and you, a giant piece of cereal (the chex warrior), have to stop them.
Value: If this is a Doom clone, why does it only have FIVE LEVELS? Shouldn't it have 9 levels like shareware doom? It is free, but still, it should have 9 levels. Gotta be said.
Verdict: Chex Quest is undoubtedly great. It could of had more levels and its a bit easy, but that doesn't stop it from being enjoyable. Download it.
