Regretris was originally developed for 0h Game Jam. Because the game jam was only one hour long, the idea behind the game needed to be simple and easy to implement. Moreover, this game was built using HTML5 and vanilla JavaScript, so some of that time was used to build the engine.

It combines the input of 2048 with the scoring system of Tetris, so you can play it comfortably on a phone or a computer. Shortly after the game jam, I turned Regretris into a Progressive Web App and added offline support. This also allows players to add it to the homescreen on their phones and to play it like a standalone app.
