@kp-cftsz I've done some research and I think it might be because DX9 isn't included with some versions of Windows 10? Are you willing to test installing it and report back? The DX9 redist can be downloaded from here: https://www.microsoft.com/en-us/download/details.aspx?id=8109
If it still doesn't work I can consider porting it to FNA which should be more compatible with newer versions of Windows out of the box. The reason I use XNA instead of FNA or MonoGame is because I want to support Windows versions as old as Windows XP. I should probably offer both XNA and FNA/MonoGame versions of my games in the future.
@pdotjpg Thanks, definitely the style I was going for.
I play a lot of arcade style games so my perspective on the difficulty might be a bit slanted. The first iteration was way too easy from my point of view so I ramped up the difficulty a bit because it wasn't fun for me. The thought form projectiles have slower deceleration than acceleration so if you change to the opposite direction or move in circle patterns they have a harder time keeping up. The spawn positions of all the thought forms get randomized each round, so I guess it's also possible to have very unlucky starts where you're completely surrounded from the get go. I should probably increase the minimum spawn distance to the player.
When I make a post jam version update I'll definitely add different difficulty modes to match different kinds of players and might even add a "casual" mode where there's no negative thoughts and you only enjoy receiving positive thoughts. Thanks for the feedback!
