Daydreamer

Daydreamer is a platformer based in a beautifully-illustrated Post-Apocalyptic World from the mind of artist Roland Womack. As the last human survivor, you are on a quest to rescue the Immortal Gatekeeper, the last hope for a dying world.
The game focuses on high-intensity Boss Battles in a classic 90s Arcade fashion with a modern twist that incorporates support characters to aid you in battle. Fight your way through 14 unique bosses across a set of imaginative dreamscapes, employing a number of weapons and abilities to overcome your foes and the environment.

[Best played with a Gamepad, unless you are keanu reeves with a keyboard]
