New Features
- Keyboard shortcuts for upgrade selection — when the buff card screen appears between waves, press 1, 2, 3, 4 or 5 to select the card in the corresponding position. Speed shortcuts (1/2/3) return to normal after closing the screen.
- Keyboard speed controls — press 1, 2 or 3 during gameplay to set speed to 1×, 2× or 4×.
- Wave rush — from the second wave onward, you can call the next wave early to earn bonus gold. Both waves run simultaneously.
- Voiced tips — all tutorial and periodic tips now have voice-over audio. A new separate Voice volume slider has been added to the settings.
- Individual volume controls — separate sliders for Music, SFX and Voice are now available during gameplay.
- Spacebar calls next wave — in addition to the on-screen button, press Space to call the next wave.
Improvements
- The game now pauses automatically when the buff card selection screen appears; previous speed is restored after picking.
- Final score now accounts for average game speed and remaining planet life — playing faster and more carefully yields a higher score.
- The skill tree now closes automatically when pausing with ESC.
- The first wave starts immediately, without waiting for a buff screen.
