"Every wall is falling all the time" is a good arcade hook. The scenery becomes the enemy, so your score is literally how long you last. And the white pixel art logo tilted on the diagonal has a nice arcade energy to it.
Real credit for the honesty on your page, too: you flag prominently that the leaderboard does NOT work in the web version, explain why, and point people at the downloadable builds if they want to submit a score. Warning players instead of letting them discover it is the right call, and it's the sort of thing this jam should reward.
But I couldn't get past the title screen. The game loads (Godot 4.7), but the screen stays almost entirely black: just the HYPERFALL logo in the top left corner and a small grey box reading "WRIT" beside it, which looks like text cut off mid-word rather than an actual word. I waited over 20 seconds and nothing changed. I followed your page instructions exactly, clicked the canvas, pressed Space to play and A/D to navigate the menus. No reaction at all.
The diagnosis I'd suggest: all the content is squeezed into the top left corner even with the window at 1920x1080, which points at a viewport or stretch configuration problem in the web export rather than a lack of screen space. Also worth noting the browser tab says "Hyperfall (DEBUG)", so a debug build got published.
I couldn't evaluate the game itself, which is a shame, because from the comments on your page there are clearly people playing and enjoying it. It looks like the web build specifically is what's broken, and since the web build is what almost everyone in a jam will try, that's worth a re-export.
