Choosing to make a single project for both low-res jam and 1-bit jam is one way to challenge yourself! It's paid off really well here though - you've done a great job keeping the visuals extremely clean, and the limited view works really well with the speed you've set to keep gameplay very fast paced but always fair.
The spotlight is a really fun addition, as I got more comfortable I found myself deliberately triggering it to boost my score faster. Would love to see it in something along the lines of a timed mode!
I did find a bit of an exploit in that spamming the input could create an impenetrable wall of bullets in front of me, but it wasn't an issue as I could just not do that :) my highscore playing normally was 22 :)
