Illvelo Swamp is a vertically scrolling shoot-em-up developed and published by RS34 for Nintendo Switch in 2021. Like Radirgy Swag, it plays in horizontal orientation, with a slightly angled perspective.

The game's title and general aesthetics draw from the original Illvelo, though this game introduces new mechanics and has a radically different stage structure. There are 100 stages in total (as a reference to the 100 bonus stages in the original Illvelo)

Gameplay Overview

Illvelo Swamp is a twin-stick, four-button game with one playable ship. The left analog stick is used to control the ship (with uniform speed) in any direction, or with the directional pad in a total of eight directions. The right analog stick can be used to control the detachable Doll (modules) independently from the ship.

Controls

Buttons are configurable in the options menu.

• Shot: Shoots a forward-facing shot
• Doll:
• Megalophaz: Generates a circular field ship that grants temporary invincibility, absorbs all bullets that touch it, and collects items. Equivalent to a bomb in other games.
• A. Shot: A toggle to turn continuous shot on or off. With this toggle enabled, the ship (and Doll) will continuously shoot as if the shot button is pressed down. This can reduce finger strain for the player.

Also, a shield appears in front of the ship and Doll if the shot button is not pressed for a short time. The shield remains in front of the ship and Doll and absorbs bullets until either the shot button is pressed again.
