A Tetris game but with a twist. Instead of lines clearing instantly, every 10 seconds, a scanner goes from the top of the playing field to the bottom and finds any full lines. When it reaches the bottom, they are destroyed. If there are no full lines when the scan finishes, you will be penalized.

Controls

Up/W Hard drop Down/S Soft drop Left/A Shift left Right/D Shift right Enter Pause/Resume/Restart J/K/Z/X Rotate piece

Settings

There are three difficulty settings, which change the points you get and the penalty for a missed scan. There are also four music tracks to choose from by pressing left/right on the music option. You can also view some statistics after you have played a few times.

Rusty

You haven't played Tetris in a while, be gentle. You will get half points. The penalty for a miss is that your current piece is hard dropped and you get no points.

Trusty

My personal favorite mode. You will get normal points. The penalty for a miss is a row of garbage blocks that pushes the stack upward.

Lusty

You can't help yourself. You will get double points. The penalty for a miss is a game over. This mode is very difficult and requires a different strategy than is normally used in Tetris.

Scoring

You get points for many of the normal things in Tetris. The main source of points is for cleared lines. You get more points for clearing more lines at a time. Because of the way lines are cleared, you can get more than 4 in a single go for some extra big points. There are small bonuses for hard- and soft-dropping pieces based on how far you drop them. There are bonuses for so-called "T-flips" where you put a T piece in a weird place by rotating it at the very end. There is a bonus for full clearing the board. Peculiar to this take on Tetris, there is a bonus for "edging", or completing a line while the scanner is actively scanning it. This last bonus is scaled based on how soon the scanner would have been past that line and not seen it this round.

Strategy

Depending on the difficulty level you choose, the strategy will differ. In Trusty and Lusty modes, you will want to make sure you have a line as soon as possible so you don't lose or get garbage blocks. In Rusty mode, you can be aware of when the scan will finish and position your block so you are ready for the drop.

Another difference is that you cannot rapidly break down your stack because you have to wait for the scanner to finish for lines to clear. This means that it may not always be the best plan to drop pieces as fast as possible.

How the Sausage Is Made

• I wrote the game in c++, using my game jam library, libgam.
• I made the art using Aseprite.
• I made the music using my hardware synthesizers and mastered tracks in Ardour.

Thanks for reading and I hope you enjoy the game. You can also check out the soundtrack on my bandcamp.
