Good job so far, You have time to improve it again if you want.

I'm going after fast iteration. I've already ripped out the parts I like, made asset loading/access consistant in code( texture, sound and font), bumped up ease of input usage and rewrote the state manager to be stacked based similar to my C++ approach. In short, preparing my framework for the next challenge. C#/monogame kicks tail.

haha,  great, I think you could add more stuff that was not in the original version.

I am just hardcoding without thinking about next challenge. Not sure I will have time for challenges.

looks awesome

Lightning is an interesting special effect. Particle implementations are always satisfying. This was a fun one.
