Such a promising demo! I haven't played an FPS in too long and you've reminded me how fun they are, even if a bit frustrating, or shall I say unforgiving at times ;)
The game ran perfectly, the sound effects were all very good (the song at the beginning was incredible) and all of the weapons I got to play with worked exactly as they should. I will definitely be trying the ones I missed in the open world mode and I am looking forward to trying out the wave mode too, love that you included one!
There were a couple moments, actually ONE moment where I was almost ready to throw in the towel but I am so glad I didn't. It was a really fun challenge and felt so good once you start finding more powerful weapons. Can't wait to build a giant arsenal in the full game.
You have a lot of talent, I look forward to the finished game and whatever else you make in the future. Thank you for this fantastic demo :)
