I like the idea. My main issue was that I didn't know how much the items cost. Eventually those pesky zombies swarmed me and I couldn't stop them killing the house. Maybe some craft-able defences would have helped
Absolutely! Time was a big issue, definitley bit off more than I could chew with this one. Tooltips are enabled for the upgrades that show how much they are (I know this is not the best solution). I'll add a comment to the description to let others know, thankyou for trying and giving feedback :)
