To be honest you have made me happy with this flashback. Since from 90s i am a real tetris fan. i still have one hand held tetris hardware from the year 1999 which I'm playing everyday. So even if its another tetris I'm up to play :)
Cheers nice game. I also like rotation on the stick geometric shape. Normally it does not have any rotation in most of the tetris versions i played.
You are right with regards to the "not standard Tetris" proposed. I have to make an update to comply more with ISO 9001 guide of Tetris here : https://tetris.fandom.com/wiki/Tetris_Guideline that I discovered today. Thank you for the kind feedback!
