A Gnowius' Challenge is a fan game created by Oshisaure using Love2D. While the development of the game is currently discontinued, a demo has been released and is available.

Gameplay

The game consists of two game modes: the main mission mode and a practice sandbox.

Mission mode

The main mode of the game makes you go through stages and asks you to complete certain tasks, similarly to Tetris The Grand Master Ace's Tetris Road. So far, 20 stages have been made.

It should be noted that the game uses immobile spin detection, instead of guideline's 3-corner. This is especially important for stages requiring spin line clears.

Practice Sandbox

This mode lets you play under custom settings, with no goal and no time limit, until you either top out or back out. You can also left-click the matrix to place blocks, and right-click to remove them. This is meant as a practice tool to train specific timings and/or Rotation Systems.

The settings you can change are the following:

  • Field rows: Width of the field in cells, between 4 and 99.
  • Field columns: Height of the field in cells, between 4 and 99.
  • Rotation System: The rotation rules in place. See below for more information.
  • Next Previews: Length of the next queue, between 1 and 15.
  • Blocksize: Size of the blocks in pixels, between 1px and 64px.
  • Field angle: Angle at which the field is displayed, between 0° and 360° in steps of 22.5°.
  • Field depth: Scale of the back layer display of the field giving the 3D effect. This is purely graphical.
  • Gravity: Speed of the blocks' fall in rows per frame (G). You can set the numerator and the denominator separately. Setting the denominator to 0 results in infinite gravity.
  • Delayed AutoShift: Delay in frames before DAS kicks in.
  • Lock Delay: Time in frames before your piece locks. Note that this game does not have move reset, only step reset.
  • Spawn Delay (ARE): Time in frames between a piece lock and the next piece spawn.
  • Line Clear Delay: Time in frames between a piece lock and the clearing of a line is complete.
  • ARE after Line Clear: Time in frames between the end of a line clear and the next piece spawn.

Note that changing field dimensions, rotation system, next previews or blocksize will reset the whole board, erasing the previous map drawn and resetting the piece sequence.

Rotation Systems

Alongside the Super Rotation System and the Arika Rotation System, the game has a few more Rotation Systems you can toy around with in practice mode.

Using Tetromino pieces

Shirase Rotation System

Texmaster World Rule

Transform Rotation System

Biased-On-Nutty-Kick-Enhancement Rotation System

Using Pentomino pieces

Pentomino Arika-Inspired Rotation System

Puyo Puyo Tetris' Pentomino Rotation System
