Reddit: help to find a MSX game title!

[emiliano]

Hi Reddit, when I was younger (25 years ago) I was an heavy player of
Philips MSX game.

To remember these old days I start playing them again, but I have a
problem! I cannot remember the name of my favorite game, so could you
please help me?

The game was a platform one. The goal, to reach the next level, is to
collect a ring and a diamond. You have to collect such items in a
certain amount of time, otherwise your "health" indicator start
decreasing. Other obstacle that i remember in the game are acid
tanks...

Please help me to give a name at this game!
