Thanks a lot for the feedback!
I have published before on itch so I felt confident it wouldn't present any issues... except I was using some crates that wouldn't work on WASM, so that was a wakeup-call. The process of getting it published wasn't an issue in the end, I just felt time got away from me, wasn't able to develop the gameplay further. Everything always needs tweaking, right?
In the end it feels like a proof-of-concept or tech demo (for bad tech), but I think I got the look that I wanted, at least.
Sound... next time!
