Thanks for playing and for the feedback!
Very nice suggestions and observations! The game's balance and the current maps are very much work-in-progress and the project is currently on hold as I don't really have a group of playtesters to constantly try this out with. But I'm sure I'll get back to this, to at least work a bit on balancing things out and especially to make more maps, to make this a nicer experience for anyone interested in this.
