Thanks! The reason why the Player can't move their camera up & down is because the Episodes in this game were designed in a "gimmick" system, where each Episode has its own gimmick (First is "Faithful to Doom", Second's theme is "Wariolike").
If I put a Blue Skeletor (Ethereal Skeletor) at the starting area, the Player would easily get overwhelmed by an unexpected flurry of punches, especially considering that the element of surprise would render them unable to move (I think?????) which would only worsen the situation.
Slime Enemies (Foul Sludges) are a tad bit unforgiving I know, that's why We're going to decrease their amount (at least in E1M1).
Fun Fact: The Red Necromancer (Dark Mage) is actually just a palette swap of the Player Character, call that being lazy/faithful to original boomer shooters!
And also for the game links, I've published this game's older version earlier when We felt like it was finished, but due to some last-minute bugs, glitches & other whatnots, We've updated the game a bunch more times, this included adding the "Vote" button, Game Exit Easter Egg, getting rid of a bugged Ground Slam Ability in the Episode 2, a few more Easter Eggs and the Blessed Level Selection Menu
Thank You again for Your extensive feedback, glad You've enjoyed Our Game :D
