Thank you for the kind words, they mean a lot to me! You can find the code here on github (a little bit of a mess rn ).
1. The graphics are a modified version of bayer-dithering, applied as a full-screen effect in URP ( this video / channel is my fav for Unity graphics stuff). Light use of URP post-processing was also used.
2.The title/end screen are built using the default unity animation tools. Just entered record-mode, moved the timeline, and then moved the camera along the path (although cinemachine could probably accomplish this better). The intro cutscene are just stills moved/scaled in a similar fashion with a worldspace canvas.
I definitely aim to make the game longer and more robust for resolutions! I designed it for a fixed aspect ratio for Webgl but had to switch platforms last minute because of compile issues. I joined the jam a bit later and ran out of time (and didn't wanna crunch like with jams in the past). Once I finish the project I hope you'll give it another go :)
