Sunder Siege tasks you with swinging a wrecking ball to destroy oncoming monsters before they breach your defenses. Between waves, upgrade your ball's power and your home's durability to handle increasingly difficult threats. It's a compact blend of physics-based action and incremental progression that appeals to players who enjoy straightforward mechanics with steady upgrade payoffs.

Absolutely great game that is super fun. I never thought swinging a spiked ball back and forth would be fun, but it's super fun. I would definitely agree it's got a strong incremental element, as the skill tree is diverse.

From an idler perspective, other than the skill that gives you "energy" every second that you can upgrade, even when you're not in a match, there's no other idle components that I can see. A suggestion to the developer would be to consider an "idle" mode where the ball swings back and forth automatically but maybe less accurately/more slowly/less damage to still encourage active gameplay. I think this would still fit with the theme of the game because you can also just keep the game idle on the skill tree after unlocking those skills to accumulate points to upgrade, so there's already idle aspects in the game.

Edited to add: The developer is fantastic and very responsive to feedback. I mentioned Cloud save not being enabled and bam it was enabled shortly thereafter.

Enjoyed the game it’s fun and interesting. I do wish that every time I went back to the upgrades menu, the zoom level didn’t reset. It would be great if it stayed at the zoom I previously selected. All in all, it’s a nice little game, and the price is quite fair.

Great concept, but it feels more like a prototype than a finished game.

A physics-based incremental tower defense where you swing a wrecking ball to defend your base sounds awesome. Unfortunately, the actual gameplay is basically:

  • Move mouse left.
  • Move mouse right.
  • Repeat.


That's pretty much it.

There's no real tower building or upgrading, very little active progression, and only a handful of passive upgrades. I kept waiting for another mechanic, ability, tower, or bit of micro-progression to show up and deepen the loop, but it never really does.

The "physics-based" part is also pretty shallow. If your ball hits an enemy without killing it, the enemy basically just gets knocked straight into your wall.

Then there are things like an upgrade literally displaying its internal name:

ug_tact_overtime_1

That really sums up the problem. There's a genuinely fun idea here, but it feels unfinished.

Give me more towers, meaningful upgrades, abilities, progression, and reasons to do something besides swing the mouse back and forth, and I'd absolutely come back to it.
