- Update v1.4.1 - Better Chests and No Chests - 16 April 2026
Very big change to how the passive effects are rolled for in chests. Passive Effect choices from chests now have a significantly higher chance of matching your current build. Should be particularly noticeable for classes with a lot of weapons available to use. Added a new Hard Mode Modifier: No Chests. Ultimate Destructor now has access to the new boxing gloves and roundhouse kicks items. Orbs are now a bit cheaper to purchase. Minor performance improvements/bug fixes. Enjoy! Bye Bye Ocean
- Update v1.4 out now - Two new weapons, three new professions - 14 April 2026
Two new weapons: Boxing gloves and Roundhouse Kicks.Boxing Gloves: Powerful and quick, but can only attack adjacent rocks in four directions (up, down, left and right). Super precise but might be difficult to build yourself a path out. Has both speed and damage passive effect upgrades.Roundhouse Kicks: Begins as a weaker battle-axe. However, it continues to kick even when using another weapon. It also has both spin speed and damage passive effect upgrades (and yes... both are infinitely scaling).Three new professions: the Martial Artist, the Shotgunner, and the Generalist+Martial Artist: Dual-wield the two new weapons, your roundhouse kicks and your boxing gloves, to MMA your way to the centre of the Earth.Shotgunner: Probably the biggest challenge so far. Can only use shotguns. But no platforms or ladders... or jetpacks... or wings... or hoverboards... or jump passive effect upgrades..…

I know... boo... but at least it might stop crashing the game on Coal-only mode (thanks Dex!)Passive Selection might feel slightly more balanced.Optimised some gun effects which will prevent unnecessary lag when using e.g. the minigun.Some other small optimisations.As always, let me know if you encounter any new bugs or anything is not working properly!

- Patch 1.2.1.2 - 19 November 2025
Removed debug label on collectors that was left visible in the last update.
- Patch v1.2.1 - 19 November 2025
Fixed most of the major bugs with various counts in the game. You should no longer feel limited to ~1e21 coal count. Collectors should do their jobs better. Item drop numbers in the later levels have been increased to match their appropriate levels. Finally - I appreciate your patience regarding the bugs in the endgame update. The code is spaghetti, and lots of sneaky int()'s were lying around messing things up. Hopefully a large majority of these have been solved now. Thanks, Bye Bye Ocean
