Treasure Hunter (199x) (Watara)

Meet the digger on SuperVision!
The goal is to collect all the treasures in the level by digging the ground and watching out for stones that fall if there is a void underneath. After collecting all the treasures, you need to find the door, which is the pass to the next level. You should act quickly, as there is a time limit.
Gameplay is traditional. This version is done well - the levels are thoughtful and interesting. Recommended!
