It’s nice,y balanced so it doesn’t get too discouraging at the beginning but it gets pretty hard quite soon. By the way, I bought this after hearing about it on the ATP podcast. **Developer response:** Thank you! I have made a number of further improvements (including introducing a Hard mode and tweaking the original gameplay), please try the latest version. ## Frequently asked questions about Celtreos ### What is Celtreos?
