BLACKHOLE

Blackhole is a 2D side-scrolling puzzle-platformer. The player's task is to collect "selfburns." At least one must be collected in each level to move on. If all selfburns are collected in the level, the time is saved. The player can also try to get a better time once he collects all of them. To finish the game, the player needs to collect a certain number of selfburns. The game contains six acts. Every act is set in a different environment and includes different puzzles or objects.
