Came to this game after I saw the last yt vid. Tbh I did not expect much since I dont play this genre of games. I just wanted to check it out. But it turned out to be quite addictive. The only thing I have to say is the balance seems off (which is understandable since its not finished). But I got to the end of progression, I have not much to do to speed up executions except upgrading execution and capture amounts, but It feels like I barely made a dent into the population. Maybe I play it wrong.
Also I noticed. After some time I have no reason to sell my pit. The reward is not worth the time rebuilding it. I think either the reward should be greater, or the player should be only able to buy the gold upgrades after selling the pit (before creating new one). Not sure if the kills from my previously owned pits still tick away after I sell them. It seems like it but to me its not really clear. That could maybe be a reason to sell my pit, since it is easier to increase execution rate that way.
One more minor thing - at one point all my resources changed to either NaN or some huge negative number, but it seems it was just a gui issue, since refreshing the page fixed it.
Overall very nice game, looking forward to the next update.
