After over half a year I returned to iron out some long-standing bugs (audio looping), added more key alternatives (especially handy for people on computers without numeric keypads), and recreated the playfield generation animation.

• Added alternatives for piece preview toggle (P), hiding the legend (H), and increasing the level (U)
• Fixed looping of background noise for Web version
• Added option to toggle background noise on or off (Tab)
• Added game-start animation to match the Elektronika-60 original even more closely
