Gridlee © 1983 Videa.

A game where the player controls a bottle-shaped character named Gridlee who has to catch colored balls (or the crystal) for points & shoot the enemies while they are overhead. Shooting enemies also awards the player points, but more importantly, the only way to pass a level is to shoot every enemy. The player knows when the enemy is overhead by looking at his shadow on the grid. Each red ball is worth 100 points. The green ball appears after catching 3 red balls & isworth 500 points. The crystal appears after catching 3 red balls, a green ball and 3 more red balls. It is worth 1000 points and must be caught before it lands since it will not bounce, but instead disappear. The green balls bounce very high and can bounce far, making them hard to catch. The player has to avoid touching the bouncing enemies, the charged tiles that flash after enemies land on them, and the worm that moves horizontally across the tiles while charging them. There is a character named Igor that spits a sticky gum-like substance, which turns the tile it lands on pink and causes Gridlee to move slow when walking on that tile. Also, if there's one enemy left bouncing for a while as the player catches the
balls, the enemy eventually charges tile after tile, which makes it dangerous for the player as the walking space is limited.
