Lovely little puzzle, and the three tricks are a clean fit for the theme. I played seven boards across all three difficulties on a laptop and on a phone (Pixel 7 size). They all cleared, the lift, drag and float cards each showed up, and there were 0 errors.
One thing worth fixing before rating gets busy. Tapping the Beautiful Mind Games logo during the 2 s splash calls localStorage.clear(). On itch every HTML game runs on the same origin (html-classic.itch.zone), so that clear isn't limited to Hexodus. I checked this in a fresh browser: I saved a fake entry under a different game's path on that origin, played an Easy board so Hexodus saved too, then reloaded and tapped the splash once. Every key was gone: Hexodus's own ("Hexodus V4" with the tricks found, plus the per-difficulty key with stats and the board in progress) and the other game's. So a player who taps to skip the logo loses their tricks and stats, plus saves in any other itch browser game they've played.
If the tap is meant as a reset, removing only your own keys (anything starting with "Hexodus") does the same job safely. Otherwise just drop the clear.
