---

This is another release has been developed quickly and for personal experimentation;
But anyone should feel free to create an issue if they encounter a troubling bug!

More modes release

This version adds an experimental new mode:

• Descent mode (accessed by running the program with a commmand line flag --descent-mode / -d (e.g. ./tetrs_terminal -d)).
• Time trial is available again.
• Tweaks to other things.

Combo release

Literally a combo release. (Not only is it the third release in close succession, but also it adds...)

• Combo mode.
• Also, a release tag is now included in the About menu for convenience (sorry that took so long, I hope it might start coming in handy from now on.)
• New bugs, most likely! (Feel free to open an issue if it's not fixed in the newest release.)

Well-named release

Finally!

• Hold function implemented.
• (Tweaks and fixes.)
• (New bugs to be discovered and fixed.)

Dedicated to Nome

Quick fix release #3

• Tweaked O-rotation! - this release adds functionality to the O-piece's otherwise visually useless rotation. It will behave like a move ('roll') to the side, and in special cases allow for O-spins!
• Other tweaks and refactors

Small Tweaks release

• Ocular Rotation System v3: More symmetry, more control, more flexibility!
• Added Cheese mode: How efficiently can you eat through 32 lines?
  • Removed "Time Trial" mode (still accessible using Custom mode.)
• Keybinds can now be explicitly deleted.
• Save file location is now mentioned in settings.
• (Fixes, tweaks, refactors...)

Quick fix release #2

• More T-spins! (+ new final level in Puzzle mode)
• Initial Rotation mechanic
• Gamemode descriptions
• A bunch of bugfixes

Enhanced Customization release

As mentioned in the readme.md, development of this may slow for a moment, due to personally being very busy with other things - but this is just one more release before that, to quickly add some more cool stuff (because why not):

• New Configure Game screen with all tetrs_engine config options finally accessible!!
  • Timings: delayed auto shift, auto repeat rate, hard drop delay, line clear delay, appearance delay.
  • Other: piece generator, preview count, soft drop factor, ground time max.
  • Moved from Settings: rotation system, no soft drop lock.
• New Electronika 60 retro graphics option.
• New Sonic Drop mechanic + settable keybind.
• Bigger piece preview now functions (up to 8 visible, was, 1).
• Better scoring formula (+buffed combos, -nerfed back2backs).
• Improved restoring of terminal state after application exit (+ crashes get logged to tetrs_terminal_error_message.txt).
• Other refactors and fixes.
• New bugs to be fixed in future releases.
• Removed Herobrine.

I thank everyone for the support (2⁶ stars :o) and hope everyone enjoys these additions

Improved savefile storage release

• This release ensures tetrs_terminal does not store any .tetrs_terminal.json file unless you request it - Make sure to toggle "Keep savefile for tetrs" on in your settings in the future!
• It will automatically try to store it in a reasonable location - see README.md.

Quick fix release

• Separated 'graphics' toggle into 'graphics' and 'colors'
• Fixed color bleed issue for certain consoles
• Fixed another crash in frontend (settings)
• Removed Herobrine
