Boomerang

You control a boy walking through a platform maze trying to collect items while being chased by enemies, which can be killed by using the boomerang. The boomerang has a limited range and, if thrown, must always picked up as it will not return to you. Compared to the PC-8001 version, where the game is 28 stages long, this port has 14 stages in total. I get a game over on purpose after completing a full loop.
