Game mechanics are frustrating and silly as intended, confirmed; but the game being stuck in a small upper-left corner of the black background (not full screen) was actually a tad annoying!
Hi @PXshadow, thank you for the information. I have installed Firefox and tried it, but it still fills the screen as expected for me. If it's not too much trouble, could you try in icognito/private mode, or with extensions disabled? I wonder if a privacy tool is stopping Heaps from getting the window size properly.
