This project is awesome. I love me some tetris, and most of the time I am content with playing the NES version. But it doesn't have the QOL features tetris' new entries have added over the years. I play on my phone, so I could download the official Tetris app, but it is sadly infested with ads and microtransactions and I'm not withstanding all that to clear some lines on the go. Enter Apotris, a tetris "clone" with all the niceties of modern tetris, and fully open source! It has features like block preview, hold mechanic, extendable list of queued blocks, and a variety of skins so you choose the one you feel sits right with you! Not only that, the gameplay is buttery smooth and I love how they added a little rumble animation that is pretty satisfying to see. I use the gba version with an emulator, but it is also supported across multiple platforms. It really comes off a game made with lots of care and love put into it. So, if you ever get the itch to play some tetris, give Apotris try!
