I initially tried to complete this without a mouse, instead using the nipple on this Thinkpad. This was pretty miserable but worked up until I ran out of ammo on the nailgun, when I realized this game does not allow pressing number keys to switch weapons and I didn't have a proper scrollwheel. At that point I had spent too long trying to complete it in my silly way to not finish it, so I went and grabbed a trackball mouse to do it in a much easier but still kind of silly way.

Anyway, the technical achievement is the main point of focus here but the vibes were still impeccable and this was a really cool take on a couple levels of an old favorite.

Despite Backloggd showing this as a Windows game, this is a purely in-browser game
