Yes it was fun and engaging for a while, a decent challenge without being too difficult overall, and the concept is a good one overall of growing and protecting your base. If you plan to keep working on it, I could see something like thronefall-style upgrades being very interesting in a game like this, where you choose different structures for different branches, e.g. automatically protect half your tree while the other half generates more essence for you while you protect it yourself. Oh yeah and I would say abilities like shooting and repairing should have a bit of a cooldown otherwise easy to cheese. Great job overall for sure!
