A fun experience worth playing.
The game's biggest weakness is the fact that the lower tiers, especially after tier 10, are way more profitable but not much harder than early tiers; to the point of maxing the selling kobold's weight with a successful free sale and allowing many failed sales afterwards. It's also nyon impossible to tell how many direct subordinates a boss kobold has if you use more than one active sales kobold per tier. The dragon looks perfect, but the kobolds could use one more weight stage, max 2.
