Cool game!
- Loved the aesthetic and gameplay loop. It feels really satisfying to make progress in a level.
- I did break the tutorial by accidentally mining the mana crystal before the checklist point came up.
- It's very easy to get overrun if you mine 2 entrances at once. I get the solution is to slowly expand from 1 path and wall off other entrances, but that doesn't feel as satisfying as managing chaos. I found myself wishing for some way to control multiple groups of units, or to set a rally point for a building.
- Owned territory looks very similar to unowned territory at a glance. You could give it an entirely different colour palette similar to zerg creep in Starcraft/undead blight in WC3, or you could highlight all owned territory when you're on the building UI.
- The building UI (b key) felt slightly too overloaded when it contains building, placing items, AI keys, deconstruct and haul items. I think if you could split those up into separate menus the UX would be improved a bit.
- You can't pan the camera in multiple directions at once. A minor problem but it does affect the game feel a bit.
- It's possible to pan outside of the map limits and get lost in the fog.
- Turning corpses into monsters is a really interesting mechanic. I wonder if it could be expanded further - for instance it could gain lifesteal if you've got a vampire corpse, or flying if it absorbs a bat corpse.
