3 things I already noticed: (Android ver)
The intro has a popping noice that probably corrisponds to the subtitles.
When pressing 'about' in the main menu, the background glitches out.
edit:
Major bug at the start. After the intro sequence, before the grocery shopping mission, the screen pans the black as the MC makes the black hole joke. The screen remains black with the ui elements and makes the game totally unplayable from there.
I'll write again if I find anything else
