I enjoyed it! At first I didn't realise that the floating things were the key cards, so for the first few minutes I walked around the walls of the map spamming grab lmao
On the first level, I grabbed the card and walked past the creature without realising it until I turned around. It didn't see me even though I was right next to it; I'm not sure if it was supposed to chase me or not. The second level was too laggy for me on the HTML5 version of the game so I couldn't get past it.
Good concept though!
