Fun game. Good to see that the developer takes suggestions seriously and responds in a timely manner. The way the idle play 'issue' is about to be resolved sounds much better now. The root cause for idle play however is still present (at least from my perspective). Late game progress is still quite sluggish. If advancing to very high levels was not intended then I would suggest to introduce a level cap and have players be ranked according to their progress in endless mode after they reach max level. Incentivising people to progress further on endless mode will in addition reduce the effectiveness of auto-turret based play.

pretty sure the ad for this said it was a traditional tower defense game. IDK about you, but I consider that to mean you place towers of various sorts to deal with the ever increasing waves of enemies as they travel a winding path to your base. A decent game in its own right, but false advertising.
