Quick initial thoughts: Pretty cool! Good music. I appreciate that you decided to add a score mechanic. The next piece preview disappearing during the line clear animation can be a bit of a nuisance. Also, the Discord link is expired.
Oh I didn't know those links expired, thanks!! I'll update it now.
The next piece vanishing is a big of a bug/hack to get around a larger issue. I'll see if I can fix it. Thanks!
I have a fix for the next block vanishing in the next build (BETA 3). Thanks again!
