Inaccuracies, visual glitches and crashes.

On https://vidkidz.tistory.com/3388, there are many faults with the emulation of the game.

• Inaccuracies.
  Originally this game had a bug where if you paused the game, you would gain a short invulnerability to spikes when you first stepped on them. This bug is not present in waflash's version of the game.

• Visual glitches.
  In level 8, the ramp you go down at the start is invisible for a short time, making the level impossible unless the user knows where the ramp ends. The same glitch happens at the start of Level 9, and the end of level 10.

• Crashes.
  The game crashes when loading level 11, every time.
