Hourheart
The world has fallen, but the Hourheart still holds the final fortress.
Defend its central tower against escalating waves of raiders, ranged attackers, support casters, armored siege units, and powerful bosses. Your core weapon attacks automatically while you spend salvage on power, speed, range, armor, repairs, and specialized defenses.
Build for the threat in front of you:
• Slow swarms with Caltrop Fields • Punish melee attackers with a Thorn Rampart • Block projectiles with an Aegis Projector • Hunt ranged enemies with Falcon Ballistae • Break armor with the Breach Cannon • Keep the fortress standing with Forge Drones
Time Repulse Pulse, Aegis Dome, and Sundering Beam to interrupt dangerous attacks. Defeat bosses, choose lasting Doctrines, and develop the Hourheart’s weapon.
Your fortress persists when a wave defeats you. You reform at that wave’s checkpoint, keep the resources and Echoes you earned, and begin the next attempt stronger. Earn 20 lifetime Echoes to raise the Terraced Bastion and hire defenders for its five new terraces.
Push through the hand-built campaign opening into endless generated waves—and return later for offline salvage that strengthens the same enduring defense.

I would be really nice to be able to see how big the range is.
I did have this in an earlier version, but it wasn't too refined, just a circle once you click on the tower. I'll see what I can do. Thanks!
Also, once the tower is upgraded to the terraced tower, each terrace/defender combo will have a different range (higher terrace have more range, stone thrower has less range than the archer). So that's 6 different ranges from the Main Tower.
Added the range visualization when the defender or tower is clicked.
A few notes/bugs/issues:
Needs a way to remap the keys, the default layout doesn't work for me.
Some screens, like the Echo pop-up one, need to be closed by clicking on the back arrow, instead of clicking at the background like most others do.
Needs more tutorials, or else a more tight-knit one: Research is available before the appropriate part, if there is any?
4x speed doesn't work at all, AND when you tab back in to the game, the speed resets to 1x, regardless of the setting.
The Help "Basics" are delightfully concise, and the "Field Manual" is waaaaaaaaaaaaaaay too verbose. I would say that the sweet spot is somewhere in between, and a lot closer to the brevity of "Basics".
Those are what I got for now, but your agent can handle all of them if you wrap it nicely, like "Here is the consensus of user feedback, make the necessary adjustments:" and then paste in the above points.
Thanks for the detailed notes! There is key remapping under Settings → Upgrade hotkeys, although it only covers purchase/upgrade keys right now—and it sounds like I need to make that option easier to find.
The 4× speed option is unlocked by purchasing Time Compression in the Chronicle for 3 Echoes. I’ll make the locked state and requirement much clearer. Returning to the tab should preserve your selected speed, though, so I’ll investigate that reset as a bug.
