Thanks for playing, and thank you a lot for the feedback!
I'm glad you enjoyed it :)
The lack of info was originally intentional, I thought the since the game is quite stat heavy it would be more accessible if I didn't show those too prominently, but I got this feedback back from a friend I forced convinced to playtest for me as well, so I am now thinking of how to make it more clear.
Right now I'm thinking to start with adding additional upgrade text that explains directly what everything does, numbers and all, and add a option to show either Direct, Flavor, or Both.
Later I might add something to show all current stats for a tower, but that is slightly more work, so on the back burner for now xD.
The Wyrm was a rather dumb oversight yeah, added a quick sentence about it on dev build. Gonna take a look at the spider web as well.
As for the meta upgrades, I hope they'll work out well, as of now my ideas are still rather uninspired.
Seriously thank you so much for taking the time to give feedback! It's super valuable since I don't really have any playtesters, and my own experience turns out to be a bit skewed.
