Clash at Demonhead

A relatively rare genre on 8 bits. An open world game, similar to Metroid. At the very beginning there are several routes available, our hero - a special agent - can choose any of them. At first, the character can only jump, shoot and swim. Then he can acquire various useful abilities: teleportation, healing, flight, invulnerability and the ability to shrink. A good idea is spoiled by a mediocre implementation: the game's graphics and music are not up to the best examples of the genre.
