Thank you for the kind words) It's really nice to see that some people played it till the end!
About the 18th level - yeah, that definitely shouldn’t happen, so we’ll look into it. We plan to rewrite the 'game over' conditions and movement events for the enemy figurines, so that issue should be resolved.
We do plan to develop the game further to make it more complete and less frustrating in some parts. At the very least, we'll do some rebalance, add calibration, and make some of the internal changes I mentioned above.
