I like a lot about this demo so far.
There's a lot of feedback to provide on this one- it's difficult to try to organize it all.
Command card options should all have hotkeys. Extra points if those hotkeys are customizable.
Shift Queue for moves and attacks feels a little weird and doesn't always seem to resolve correctly.
Determining the edge of the map from the fog of war is very weird - I'd recommend different colors for this.
Losing an entire coven's production uptime for upgrades is very harsh.
Populations being per coven is extremely weird to keep track of - needs some kind of UI in the corner like SC2.
Witch King doesn't appear to benefit from any upgrades which makes him slow and clunky as you upgrade harder.
Unsure if upgrades have an upper limit.
Ranged units bodyblock each other a lot.
Evil Eye is cute.
Getting an explanation of what the upgrade does only after investing in the upgrade is weird.
Being able to sacrifice upgrade structures for more powerful units would be cool.
Select all army hotkey would be useful instead of doing it through command cards.
Select all army through command cards seems to be limited to only units from that particular coven, feels weird.
I hope the pixel artstyle is the winner in this battle of styles.
It feels like this game rewards passive play instead of active, aggressive play? Waiting for units to spawn hurts me - can I sacrifice Witch King HP to turbocharge my summoning rates or something?
Maybe I simply missed it, but it's kind of unclear what benefits any particular artifact bestows upon a particular coven.
Some kind of jump between bases with the camera hotkey would be cool.
Summoning Circle rally points do not seem to take effect for the currently-summoning unit; only the next one?
Effectively scouting the scrolling worldspace as it wraps in on itself is extremely weird.
Main screen with options is absolutely adorable but not being able to adjust music volume in-game feels bad.
Probably more stuff - I recorded a blind play! It'll be over here when it's done processing:
