Commander Keen jump down into this big-ass pit full of peril. I suppose it is perilous, if you aren't paying attention. "Keen 4: Secret of the Oracle is the first episode in the Goodbye, Galaxy! series. Keen must explore the Shadowlands to find and rescue members of the High Council of Gnosticus IV who have been kidnapped by the Shikadi." from http://www.shikadi.net/keenwiki/Keen_4:_Secret_of_the_Oracle ... https://www.youtube.com/watch?v=SrcxKuwpyM8

Behold the boss battle. Bilsy Beezlebubb. Spelling?. I think that will do it on this one. "Jazz Jackrabbit 2: Holiday Hare ’98 was the first add-on for the game Jazz Jackrabbit 2, denoted by its version number, 1.23x. The game, unlike previous Holiday Hare installments, had to be purchased. This is also the only ‘add-on’ to not include a JCS. HH ’98 included three new single player levels created by Jon MacLellan, a new tileset (with a day, an evening version, and a night version), and three reskinned bad guys. The enemies are: Xmas Float Lizard, Xmas Lizard, and Xmas Turtle. The ‘add-on’ also includes a new piece of music composed by Alexander Brandon. Jazz Jackrabbit 2: Holiday Hare ’98 was only released in the United States, but also formed the basis for the European add-on The Christmas Chronicles, which was basically Holiday Hare ’98 released with the 1.24 engine." https://www.jazz2online.com/wiki/Jazz_Jackrabbit_2%3A_The_Christmas_Chronicles ... https://www.youtube.com/watch?v=ZTuwg9wTwEE
