This game looks super good, well done on the visuals. I love how the outline around the assets makes them pop out a lot more. The lighting in the dark setting gave the game a nice spooky mood as well. The alien horde wrecked me the first time through as I was being slow and looking around.
I had a bit of trouble playing the web version as I'm on a laptop atm running a bit smaller than 1080p , and the game opened so big it had scrollbars horizontally and vertically! That said I was still able to see most of it. Otherwise, I felt the game was more fun to run around than shoot, there seemed to be a small delay for me from when I clicked to when the round fired.
Overall a really nice looking game that may need a few tweaks to gameplay to perfect it. Well done!
