I feel like this is unplayable in browser if you have more than one monitor :D It doesn't capture the mouse, so you click on the other monitors the whole time.
The style and art is very great though! And I love the idea!
Feedback:
I would really like an explanation in the game what I have to do. If you run and rightclick you can shoot, but have no animation for it (other than the particles), and it would be cool if the "toxic sludge" would get smaller and smaller till it disappears, instead of just plopping away :)
EDIT:
Might again be a Brave Browser Bug (Security Feature?)
