This is a cool little tetris-like! Spelling 4 letter words is a little tough. The slight gap between pixels is effective to sell the 90s LCD look. Music would go a long way, even if you used the classic Tetris theme. The hard lock to the glyph grid is a bit jarring, it would look much nicer if you animated each step of 8 pixels. 8 pixels is also pretty large on such a tiny screen, You could probably get away with 6 using a 5-pixel high font - that would give you a much taller chute to drop glyphs. Very cool.

Thank you for the really thoughtful feedback. I never considered I could've gone 6x6 on the grid, that would've opened up my options considerably. I also thought there's no way I could've composed worthwhile music with a single sound channel, but a lot of the other submissions here definitely proved me wrong. Thank you again!
