The visuals were really impressive with this one, my favorite merc was the brain slug guy that just bashed his head against the ninja king haha. I'm not one for idle clicker games like this but I still really enjoyed this. Some feedback though:
I think if they delay between clicks was shorter or non existent it would make it a lot more satisfying.
Some of the other comments mentioned it but I wish the mercs didn't despawn between rounds, it almost felt like having them manage my money was a waste of a perfectly good merc when they despawned.
One other nitpick I had was the text inconsistency with the HUD elements. Some were in a different font but that's not really a big deal.
Other than that, this was a pretty good entry and I feel like it could really expand exponentially outside of the jam.
