Honestly, I don't know why I bother, because all feedback gets shut down immediately -- if not by mods, then by other players, but still...
- on PCs with good CPUs and HDD the game works well, doesn't lag more than the flash version (because of the backend), but animations are smoother
- on slower PCs or laptops, it works about 10-20% worse than the flash version
- on both high performance and lower end machines, at least one CPU core is constantly at 100% while the game is open (when the browser window is not focused, the CPU goes down close to 0)
- seems like it doesn't use as much RAM as the flash version, but needs more testing here to confirm
- apart from the bugs, which may be known or not, if the performance issues will be fixed, it could make a swell game out of it
