Super solid game. I struggled super hard with the puzzles. I'm clearly not very creative.
I did have a slight problem after I got trapped and killed on my first run. When I restarted the monster spawns went from few and only when I was away from the spawn location to NONSTOP. It got to a point where I just stopped shooting at them as they'd just instantly spawn right back two feet away. I managed to beat it with this happening, but it was very tedious.
But still, my experience was enjoyable and I hope to see more games from you in the future.
