WOW I didn't expect someone to write such a detailed feedback comment, thank you ❤️
I agree with everything you said.
We run out of time to implement better FX for hitting enemies (they only slightly turn red as they loose hp).
On UI too, everything will be pixel art (except beam and densoul)
You pretty much foretold what our Steam release will have: there will be 21 levels (with the plot we had to cut on) each with a map layout including specific densoul structures. Endless mode will be available after you beat the final boss, so you'll have some ready to go ideas 🙂
