Manic Miner: Super Pre-School Edition

Manic Miner - Super Pre-School Edition is MM hacked so that you can walk straight into the portal in each cavern. In fact, the player has to move quickly in "Solar Power Generator" and "The Final Barrier", or else they will lose lives after vertical guardians collide with room elements, and in "The Sixteenth Cavern" inaction will get the payer killed by a horizontal guardian. The game was an entry in the comp.sys.sinclair Crap Games Competition 1999.
