- Released version 0.8.8.
- Pooled projectile sprites. Towers now reuse projectile instances instead of allocating a new sprite for every shot and destroying it on hit.
- At very high gem counts on 4x speed this drops thousands of per-second allocations to near zero, easing garbage-collection pauses and per-frame display-list churn in late-game runs.

- Released version 0.8.7.
- Paused the game when the browser tab is hidden so the GPU context is not driven in the background, reducing the chance Chrome drops the canvas in favor of another tab.
- Redrew the selected-tower range circles automatically after a WebGL context loss is recovered.
- Added an overlay with a reload option when the game canvas cannot recover from a context loss on its own.
|
| May 17, 2026 |
- Released version 0.8.6.
- Added crash and memory telemetry so late-game browser-tab crashes can be diagnosed without local repro: uncaught errors, unhandled promise rejections, WebGL context-loss events, and periodic heap samples are now reported back from the game.
- Freed dead enemies from the Phaser display list as soon as they die instead of waiting until the next wave starts.
- Skipped already-dead enemies in the per-step aura reset to stop wasting work on cleared entries.
- Invalidated pending pathfinding requests when a round is repicked so a stale result cannot apply after the round is torn down.

- Released version 0.8.5.
- Moved survival high-score checkpoints from level 101+ to level 501+ and made checkpoint email optional.
- Cleared stale projectile and target references when towers are transformed or waves end to reduce late-survival memory pressure.
- Hardened repicks so destroyed round gems, selection state, and placement previews cannot linger after returning to placement mode.
- Added extra placement guards and reduced per-frame targeting allocations to lower heap pressure during very long survival runs.
- Stopped logging successful background telemetry writes in the browser console during long runs.
|
| May 7, 2026 |
- Released version 0.8.4.
- Added level 100+ high-score checkpoints so survival runs are saved after each completed late-game level.
- Prompt for name and email before continuing past level 100 so checkpointed scores are not anonymous.
- Cleaned up stale tower references from repicks and placed special combines to improve very long run stability.

|
| Apr 20, 2026 |
- Released version 0.8.2.
- Replaced 3x speed with 10x speed for faster late-game play when the device can keep up.
- Added FPS and simulation step-cap telemetry so higher game speeds can be monitored safely.
|
| Apr 20, 2026 |
- Released version 0.8.1.
- Fixed a late-game freeze when flamestrikes kill the final enemy during wave cleanup.
- Hardened transient visual cleanup so wave-ending effects cannot restore destroyed references.
|
| Apr 19, 2026 |
- Released version 0.8.0.

- Rebuilt the game bundle against Phaser 3.90.0 for the next release cycle.

|
| Apr 18, 2026 |
- Released version 0.7.1.
- Restored Star Yellow Sapphire's combat stats to 180 damage, 0.8 second cooldown, and 121 range.

|
| Apr 17, 2026 |
- Released version 0.7.0.
- Added a Speed control with 1x, 2x, 3x, and 4x gameplay modes.
- Refactored wave timing, projectiles, and spell timing so faster speeds preserve gameplay outcomes when performance allows.
- Added automatic speed fallback to protect run accuracy on slower machines.
|
| Apr 17, 2026 |
- Released version 0.6.4.
- Fixed minimum-speed handling so enemies with a minimum speed can no longer be slowed below that floor unless they are stunned.

- Restored the Special Gem Recipes hover details on the Play page.
|
| Apr 15, 2026 |

- Fixed Mystic Black Opal and Star Yellow Sapphire so both aura buffs now apply together instead of overriding each other.
- Updated Lucky Asian Jade's description to mention its bonus gold effect.
- Adjusted slow and minimum-speed logic so late-game enemies can still be slowed correctly.
- Reworked enemy path movement to prevent late-game vibration, freeze, and focus-related movement glitches when frame times spike.
- Hardened tower placement and removal input handling to reduce frozen-rock and stale-selection issues in long runs.
- Fixed score submission input so names stay stable across runs and the letter R can be typed normally.
- Removed extra effect logging and tightened frost/flame cleanup to improve late-game stability without re-enabling floating crit or gold text after level 100.
