This is a really fun game to sink some time into! I can't wait until this gets dropped, Day 1 purchase for me when you release on Steam. :)
I did have some thoughts for your consideration:
- Peon happiness could be shown as an overall percentage or just color the sprites a different color depending on happiness to get a feel for the overall happiness (i.e., light blue for happy, pinkish for unhappy, etc.) I'm not sure if independent happiness per peon is feasible given the lightweight nature of the game and the lag that can happen in incremental games of this kind (i.e., large populations with multiple things happening all at once) but I'm not a game dev so I'll leave that to you.
- I'm unsure if I just didn't get to these recommended skill tree/building upgrades or not so ignore it if I just didn't see them.
--- 1. blue shard power to convert trash to cash with 50% reduction from building/talent upgrades (essentially to clear up clogged buildings. 2. Add a function of the compressor to recycle a peon (or peons on future uses) into shards and/or convert yellow shards into cash. 3. an addon to the Catapult that lets you use the cannons to blast the clouds while they are hovering over the pit to automate the process, as the Compressor imo is just far more useful (from what I can see in the limited demo anyway) than the Catapult is.
I can't wait for this to get a full release!
