Game looks really promising! The stylized characters are great, the music fits the genre.
Ofc a lot is missing since its a tech demo, but here are my observations:
There performance seems good, but it was noticeably worse when moving the camera while being zoomed in a lot.
A cow started flying.
A colonist hunted an alpaca, which seemed to be a big undertaking. The chad alpaca just went to sleep multiple times after taking 5 bullets and still being shot at. The hunter wasn't very good. His first shots were pretty accurate, but somehow alpacas are harder to hit when sleeping. He shot around 30 times and didn't land one shot.
My dudes were sent to build a house, but my idea to build it next to a mountain was a bad idea, the walls refused to be placed right next to dirt blocks. The stockpile area also couldnt be renamed even though it had this pencil icon next to it.
Hotkeys for managing time is nice, but hitting space bar to pause would be even more important imho. Tooltips are also needed because the icons aren't always self explanatory. The harvesting icon is a bit weird.
And of course there needs to be a double click to select all similar items function. Having to select all burgers/medikits while holding shift is still a bit tedious.
