With and without the color filter, this looks amazing! It plays really well and feels very polished. I like the way you handled the diagonal aiming, I wish I had thought of that! It was really fun, I beat the boss on my second attempt - but had to use everything the map had. Seems like a good difficulty.
The only thing I could complain about would be, that the background seems somewhat random and I think the margin for the dodge is a bit too large, I did it by mistake many times (played on eyboard). But all my respect for the amount of polish and how well it works, that's very solid for a jam game!
