Looks great. Instant buy for me as an Arkanoid-fan. Hint: the 250 Blocks big PRG-file probably will not load on stock OS. Why not using a modern cruncher? With Exomizer I got the filesize down to 65 blocks.
Technical Note for VICE & Real C64 Users:
Please avoid using traditional disk loading (.d64) for the .prg file, as the game utilizes almost the entire 64KB RAM (up to $FF4F). While compression (Exomizer) is possible, I do not recommend it due to potential memory conflicts with the decompression routines. For a flawless experience, please use the 'Inject to RAM' feature in VICE or load the .prg directly. This ensures all 133 sprites and complex IRQ routines initialize correctly without interference
