Hi all, I released a new version of the Gem Worlds demo today. This includes a couple of major changes, namely, terrain. Every level includes: - Teleporters! - Light Stars: they eat dirt and move in a pattern) - Receding walls that spring up once you walk over them, blocking things, and then reset after a few turns My hope is that these few elements will add more interesting interactions between things in-game. Also, the fifth and tenth level now include locks and keys. While the exit is immediately available without collecting any gems, you need to find 1 or 3 keys to unlock the exit. Finally, I fixed a ton of bugs, including some nasty performance bugs that caused ~10 frames to drop every time you move. As always, let me know if you have any feedback! I made these changes in direct response to player feedback, and I hope they are fun; let me know what you think.
