Gameplay

Caution: tiles are drawn separately as part of a larger bitmap (design decision). As a consequence, rendering is slow and resource-demanding. Play with patience. 🤗

The game implementes old-style pixel-oriented user interface. The meaning of each tile and the rules of the game are described below.

Tiles and represent empty space and a wall respectively.

You control the Hero , yellow twisted rectangle with small cross in the upper right corner. The Hero moves upon pressing Left and Right in a respective directions. It jumps on Up. Jump is interrupted upon Left, Right or Down. The Hero falls unless floor is reached.

The aim of the game is to save (collect) all Friends from captivity by enemies. The remaining amount of captured friends is listed in the control panel on the right.

The game proceeds as long as there are friends in captivity and the Hero has hearts . Collision with an enemy decreases the amount of hearts by 1. On contrary, collected heart increments total amount of hearts by 1. If heart count drops to 0, the game is lost.

The Hero has bullets to fight enemies. Use w, a, s or d to let the Hero fire a bullet in a respective direction. If a bullet collide with an enemy, the enemy disappears.

The game is a multi-level maze. Use portals to reach another levels. Portals are tile with numbers on it, e.g. .

The game could be paused and resumed via Pause button. The player could exit the game by pressing Esc.

There are several kinds of enemies with different behavior.

Picture	Description
	Tongue moves in the horizontal direction. If wall or portal is met, the tongue changes its moving direction to opposite.
	Gremlin behaves similar to a Tongue, but in vertical directions.
	Alien behaves similar to a Tongue, but in diagonal directions.
	Triangle moves in a horizontal direction until a wall or portal is reached. Then it appears next to the nearest obstacle in opposite direction and keeps moving.
	Water drop behaves similar to a Triangle, but in vertical directions.
	Moves of a Jellyfish could be in any direction and selected at random.
	Skull doesn't move, but waits. If a bullet or the Hero itself is detected near a Skull, it jumps onto the Hero with 0.2 probability.
	Monster moves alongside the floor in a selected direction.
