Great feedback, thank you so much! Genuinely, it's really nice to get real, constructive comments on what we've been working on.
Totally agree with everything here, and we'll definitely be addressing these observations in future releases.
One of the biggest challenges as a one-man band is performance tuning and defining minimum specs. I have my Ryzen 7 / RTX 2070 machine and that's it, nothing else to test on. There are, however, ways and means and I'm certainly going to look to ways to disable certain features to get better performance, as well as tune what's already there. Totally agree with the "toxic water" - I wanted a way to prevent players from simply swimming to the objective on levels with lakes and rivers, so need something better to address that.
Again, many thanks for taking the time to send this feedback, and I hope I can continue to build on what's there and make it all a little more entertaining to play!
