Digtet

Made for the Compo Ludum Dare 48.

Digtet is like Tetris, but instead of building up you are digging down.

Tetromino can fall as long as they overlap what's already in-place or one of it's square's top touches something. You can lock a tetromino when only the latter requirement is met. You can't move a tetromino (expect drops) if it create an overhang.

This makes the moves more restricted than regular Tetris, but at the same time it allows placements otherwise impossible. It's heavily inspired by the TGM series and DTET, with rules allowing high speed gameplay and permissive moves that compensates for the restrictions above but must be fully exploited to get a good grade.

The goal is to have the highest grade possible, S. To do so you must clear the level 999 with an A+. As your grade increases it becomes more important to do tetris and combos.

The difficulty tables are very rough, I did not have the time to balance it. If I had more time I would have added animated backgroounds, going deeper and deeper into pits.

Default inputs on a QWERTY keyboard and Xbox controller:

- Move: arrows left and right, d-pad or left joystick

- Hard drop: up

- Soft drop: down

- Rotate left: [X], (A)

- Rotate right: [C], (B)

- Instant DAS: [Z], (X)

- Hold: [V], (Y)

- Start/pause: Return, Start

Keyboard inputs are scancode based, they should stay on the same place not the same letter on another layouts.

Controller inputs uses [Lazẏnput](https://github.com/Sentmoraap/lazynput).

Press tab to open/close the settings menu. 

If you have graphics errors, please run the debug OpenGL build and report the errors. 

Some genral info and tips:

- You can move and rotate the tetrominos during ARE.

- You can keep the DAS charged without moving by holding left and right.

- Hold swaps tetrominos in-place with the same rotation and using wallkicks. Pending rotations are applied. You can swap the same tetromino several times.

- Soft drop locks, hard drop doesn't. Hard drop and gravity skips past holes until the tetromino cannot be any lower. Pres soft drop at the same time to lock the tetromino in the first place possible.
