Just submitted my entry into #pico1k 2023. It's a shmup inspired by Lazy Dev Academy's first shmup tutorial and I tried to pack as much polish into 1024 compressed bytes that I could!
Play it here: https://itch.io/jam/pico-1k-2023/rate/2258186
Would've liked to have the enemy wave gliding from side to side if I had more bytes left, as it's a bit too static. Got to the point where some of the number values had to be "how they ended up" to hit the size limit.
Next time I'll release my entry at the deadline and not before...
