Really snappy controls and nice graphics, though jeez, I am not a good gamer please give me a couple of health points!
Unfortunately, it took me 3 tries to run this game.
Idk why Windows 10 gave me so many issues, but I thought I'd let you know (and anyone else wanting to properly rate this game)... oh do I miss the days of Java Servlets...
1. Windows 10, latest consumer JRE from oracle, apparently out of date?
2. Windows 10, latest developer JDK, runs... but uh, the frame draws are flickering and some sprites just won't show. 
3. Ubuntu 20.04 LTS (can't upgrade for GPU reasons)-- runs just fine with the latest openjdk JRE from apt... which is funny because so many things are not up to date.
