What's New in Kerthunk

1.0.1

October 20, 2026

The bells are now proper bronze bells, so they are easy to tell apart from the other pieces. Daybreak's par is a little kinder. Small fixes and polish.

Really fun

You pick a ball (cannon ball, soft ball or bolt) and knock the animal builders' towers off their little platforms, trying to clear every piece in as few shots as you can against par. Wood, glass and stone each react differently, so a water tower or a stack of logs comes down in its own way. The tabletop world is charming, with a train, a windmill and seasons that turn from summer to autumn to snow. 200 levels, an instant replay for the big collapses, and no ads or in-app purchases. Buy once and play offline. Highly recommend.

Well, there goes my productivity

Downloaded this thinking I’d play for 5 minutes. That was a lie. Ridiculously satisfying and way more addictive than it has any right to be. 10/10 would waste more time.
