Courageous Perseus (カレイジアスペルセウス?) is one of the very first Action RPGs from Japan, being released one month before Hydlide and in the same month as Falcom's Dragon Slayer. However, while the other two have spawned successful series, Courageous Perseus has been mostly forgotten.
You play as the legendary hero Perseus who sets out to an island full of mythical beasts in order to save the Pleiades Maia, Celaeno, and Asterope. Perseus starts with 2000HP, but his health is constantly being drained one point per second. Enemies are attacked simply by bumping into them while holding the Space bar pressed.
