Went through some Arcadia/2001 family games again, as usual the better games were the odd arcade ports. I rolled a port of Astro Invader/Kamikaze, Crazy Climber and Spider.

The former and latter play fine (just uglier). Crazy Climber is a bit simplified in that you just move using singular directional controls to climb without having to worry about what limb to move. This means you don't get to grab on to the chopper as you'd normally do, instead it lowers a ladder and you then go down using the chopper to grab other climbers for bonus score. The dangers are also less varied.
