Gem Worlds v0.7.1 Patch

In this patch:


  • The exit portal no longer appears immediately after the level starts
  • The title screen correctly states the game version as v0.7.1

Gem Worlds v0.7.0 Update

Today, I released Gem Worlds v0.7.0 (demo). This version includes:


  • The ability to rebind any and all in-game controls. The tutorial also mentions the correct keys.
  • Some new sound-effects (e.g. player melee sound, Nana's shop sounds)
  • Chests now visually show what you got from inside
  • The tutorial now suggests keyboard keys for skills
  • All items more clearly state what effect they have when used
  • Buffed light crystals (brighter, longer duration, brightness and duration both stack)
  • You now get a tutorial/hint when you first hit 150 gems, that you can buy some skills from Nana's shop.


I also fixed around 12 bugs, including:


  • Bees no longer co-occupy spots with other bees, boulders, and other things
  • Pressing space while hovering your mouse over an item button should no longer randomly consume that item
  • Fixed rare cases where key maps generate without any keys
  • You can no longer use items after exiting a level, before the next level starts.
  • Dying at the edges of the map no longer makes the camera go briefly off-map
  • Dying while time is stopped no longer makes the next level look like time is stopped
  • Exiting while time is stopped no longer makes the next level look like time is stopped
  • Pressing ESC while the level is fading in no longer makes the menu look semi-transparent
  • Resting after aiming a skill removes the skill aimer arrows
  • Quitting to Nana's shop during the tutorial no longer shows the tutorial in-shop
  • You should no longer be able to buy the fireball skill, let alone for zero gems

Gem Worlds v0.6.0 Demo Update

Today marks the release of the v0.6.0 demo version of Gem Worlds.

This version includes one major change: everything (including you) now moves at the same time. This resulted in many subtle changes, including:


  • Monsters no longer attack you when you move next to them; they do when you're adjacent to them, and then move away
  • One-heart monsters are generally not able to hurt you significantly
  • Lots and lots (and lots) of timing (race-condition) bugs no longer exist, since everything moves at the same time


I think these changes make the game more interesting, and more forgiving of bad moves; plus, you can plan your reaction better.

I made a significant change to how the game looks:



Overall, it looks more stylish, but individual elements "pop" less. If you have any trouble distinguishing important elements, let me know, so I can make adjustments.

Some other small changes:


  • You can trigger skills with the keyboard (Z, X, C, V keys)
  • Fixed a bug where you couldn't equip skills on a new game
  • Added a full-screen option in the options menu
  • Keys act more like gems (you move onto their tile when collecting them)
  • Fixed lots of bugs


Gem Worlds v0.3.1 demo update



Today marks the release of the v0.3.1 version of the demo. The previous version was 0.3.0 (incorrectly labelled as 0.1.0). Changes include lots of quality-of-life improvements, as well as a crash fix:


  • Fix: the game crashed for some players
  • Fix: players with corrupt save games now have the hammer skill
  • Fix: the right side of buttons on the title-screen weren't clickable
  • Fix: tooltips/hints for skill buttons and items now correctly appear again
  • Fixed several bugs around changing skills (e.g. click hammer, then fireball, then something else) incorrectly showing aimer arrows
  • Added the keyboard binding to tooltips for skills and items
  • Rebound skills to ZXCVB and items to 1234; this is also one-handed friendly (accessibility)
  • Nerfed fireballs. They're now shorter-range (more dangerous to use), have a longer cooldown, and no longer destroy destructible walls
  • Skill buttons now appear disabled/grey while cooling down
  • Smaller binary sizes going forward (this update is around 500kb)


As usual, if you have any feedback, please reach out via the Steam discussion forums, Twitter, or Discord. I really appreciate all the feedback I got so far (which made up most of the changes in this build).

Gem Worlds Demo now available



Today, as part of the Roguelike festival on Steam, you can try out the Gem Worlds demo. It contains an entire slice of the game: one biome with ten levels, three monsters, five skills, and mines.

If you have any feedback on the game, or if you would like to report bugs, the best way to reach me is to post something in the demo discussion forum on Steam, or to reach out on the Deen Games Discord.

I'm really excited to hear what you think!
