Thanks for playing! Yeah the web version seems to crash a lot for people for some reason. Some people said the Windows build did as well.
We unfortunately did not put as much time into the shooting and movement mechanics as we would have liked too.
The enemies blending in with the environment was mostly on purpose to make game a bit "trickier" but the general consensus of users seem to think we should have contrasted them a bit more.
Thanks again for trying it out and leaving a comment.
