This was exactly what I hoped it would be. Fighting the enemies felt great, seeing arms and legs fly off felt great, having a small economy to keep things going felt great. The only issue I had was that WebGL kept "losing context". I have a video of it happening if you want to see it, just DM me in discord (should be same username). The solution I found was to go to chrome flags and enable webgl in both developer settings and extensions.
The only other things that felt like they needed more clarity was the companions, and the cost of damage taken. Both of these clarified themselves after trail and error, but my first reaction to winning a match was "why am I negative 5 gold?". In a similar way, when I bought my first companion, the green name wasn't enough to tell me "I'm friendly, don't kill me." so I immediately slaughtered them. Again, seeing the negative 300 gold told me what I did wrong, but with so much UI and stuff to read, those things didn't fully click until midway through my play session. Maybe a pop-up at the end of match one, and the start of the match after a companion purchase? Maybe it's just me though.
That being said, my play session was a half hour. This game is super fun, and addicting. I had to try all the different weapons, and made sure I was the undisputed champion. I can't wait to see what you have in store for it down the road. Great job!
