I loved the design and soundtrack! The control scheme was very interesting! I think some quality of life additions would be really nice such as a tooltip window that tells you what you need to build something or just what something you've built does.
There's a good bit of waiting for actions to be done where I'm not sure if any of the little creatures are actually coming over or not. Something to counter this might be making a little icon that lets me know a creature is on it's way while I'm clicking and holding for creatures to come over!
I'm also never sure if I actually have all of the supplies I need to build more, so maybe making the little silhouettes red if I don't have what I need would help to inform me whenever I'm trying to build something!
I really liked the little animations of the creatures running around and always had a little dopamine rush whenever I built something!
Overall a game I would play again! I think it's very impressive after 72 hours of work and look forward to the Steam release! Thank you for making this!
