A 1983 Spanish cult hit from Paco & Paco (aka Indescomp), Bugaboo is a simple platform game were you have to jump from ledge to ledge, to reach the hole at the top of the cave, and freedom.
Only thing is: there’s a big yellow dragon out on the loose for you, and if it sees you it will eat you. Thankfully you can hide in places it can’t get to, although the precision of your jumps is down to how well you judge powering them. Hold down the jump button to jump farther; release it to start the jump.
It’s easier said than done, but a challenge at least worth attempting, and fun to die trying.
It’s also worth noting Bugaboo‘s introductory animation sequence, which depicts a crash landing from space onto a planet, and which was quite innovative at the time. Ah, how times have changed!
