Cramped Room of Death

Brave adventurer Lance loved to party, but one night he ate too much and fell into a deep sleep. The vile Vizardians then stole his treasure and even took all his weapons, leaving only his giant spear. Lance entered the catacombs of death to confront the thieves and recover his lost possessions, but he soon realized why the spear was left behind: It barely fits in these cramped rooms! In this challenging dungeon adventure, each room is a brain-teasing puzzle with tight turns, deadly traps and no margin for error. All you need to do is jab every enemy with your giant spear to unlock the next door... but sometimes you can’t even turn to face them, because the hallways are too narrow and the spear is too long. Sliding blocks, crumbling platforms, spiked floors... you’ll have to plan your moves carefully if you expect to recover all of your stolen treasure. Features: • 5 different stages • 170 unique rooms • Secret levels to discover • 5 distinct enemy types • 12 types of traps and obstacles • 10 different ways to die • 12 unlockable character skins • A special key that can be used to make levels easier to clear
