So I went through this again and was able to interact everything I couldn't before. Also, I think some of the problems stem from playing it in fullscreen mode, to let you know. I think the idea of a sim-esque crafting world from which you can use the resources in a tower defense area is really really cool and I wanna play this when it's further developed. I found having using wasd as movement and mouse for interactions made it awkward to use the enter key until I realized that the arrow keys were also available. I think having space do the same thing as enter would be nice. The house in the "W" world didn't seem to have any collisions and I could walk out into black space. I noticed the digging reticule where your cursor pointed was offset from where I was actually digging. I couldn't figure out why I couldn't craft a cannon, then I figured I needed throwing stones, not lava stones to craft it, but that didn't work as well. One thing I'd say the game would need is some sort of obstacles or "game-y" mechanics in the sim/resource gathering worlds because without it would quickly feel very much like tedious and grindy busywork to get back to the tower defense area. I think this was all in all a really interesting concept and, like I said, I wanna try this out after more content is added.
