It's been quite a few years since I last worked on my Squarez replica for the PC called ClusterStorm written in C# using XNA. I recently released Beta 12 which is a much closer clone of the PSP version which uses the same scripting of enemies. I'm also messing around with some global leaderboards for the game. To use the leaderboards you need to create and account on my website at GlobWare.com, then use that same username and password to sign in when playing ClusterStorm.
You can download it from here.
It requires Microsoft's XNA 3.1 redist and .NET 3.5. Links to both are also listed in the download section.
