- cool title screen and great background music!
- I didn't like not being able to build stuff during eclipse because I spent the whole bright time on scavenging resources and then couldn't build more towers during eclipse
- dragging items from inventory does not work: I just have to click an item, then move the mouse to where I want it and click again
- the base area was laggy for me, but I am on an old laptop with integrated graphics, so that's probably not a common issue
- some SFX when hitting enemies might be nice, sometimes it was hard to tell if I was hitting anything
Edit: oh, and I got stuck in a wall after stepping on a teleporter
