Thanks very much, very kind words!
The game was made for a jam, so I'm not planning any major updates. I've fixed a few bugs in 1.2 though.
The strange walls were because I released a real quick update before heading off for a party - and I'd forgotten to make the invisible walls actually invisible. Whoops!
But yeah, planning to make a much bigger & more intricate follow up to this, with much more to do.
Oh, and press Q to equip the scope.
