Day 8 Hard - Endless mode - Forgemaster
I've played this game quite a while. Playing with the new class in hard - endless mode the game turns literally unplayable after a in-game week. There should be a tweaked version of the effects enemies can have to reduce the amount of lag. For example simply turn enemies red when they're on fire, just like venom works. Instead of the cluster of flames that kills my fps.
Aside from that, the game seems to be fairly balanced. Sadly the limit of buildings is a turn-off when it comes to endless plays.. And makes the game terribly boring and repetitive once you beat it once. Since the game itself limits you to a single strategy. Why i can't make giant walls and have 80+ archers, or make a giant kingdom with 100+ infantry and lots of farms to keep them fed.
A simple option check to remove the limit of buildings would be awesome and i believe not actually hard to do. And give way more gameplay.
As for the AI. A flag for melee / ranged / support units would be awesome. Plus an option to make units hold they ground and simply attack anything at range instead of chasing enemies. For example the clay golems of the forgemaster would rarely use they ranged attacks while the iron golems were tanking the bosses, and it was simply they ability to explode and respawn very quickly what takes them down.
Right now, the main feature i'd love to see is just the simply fact of having an optino to remove the limit of buildings, and tweak the special effects for better performance late game. (Enemies growing stronger while keeping the same numbers after day 10+ would also be a nice way to keep the difficulty going without burning out my pc).
Removing the level limit would also help, since otherwise you'll just end with a lot of aether that can't be used for anything.
