Derenoid is the second “bonus game” created by Yanna Curtis in DERE EVIL.EXE. It is clearly inspired by old brick-breaking games like Arkanoid. The game features Knightly below a paddle that is used to bounce a ball up to several rows of bricks that break upon contact with the ball. There are bumpers on either side of the level that usually bounce the ball slightly upwards. Yanna claims that the game is “impossible to beat,” and her corruptions usually attack Knightly before the player has a chance to beat the level. In this case, Yanna offers a third bonus game, and it appears that Knightly is returned to the next level of DERE EVIL.EXE.

Unlike Dere Quest, it is possible to beat Derenoid. When a player clears all the bricks in the level, they receive a message from Yanna that begins a URL trail that eventually leads to Dere Quest 2 and other information hidden in the official website of AppSir, Inc.
