Code variation 1 of 12Related to a standard feature

Pythons in the cassette and Electron versions spawn up to 3 canisters on their demise, but this rises to 5 canisters in all other versions.

Tap on a block to expand it, and tap it again to revert.

Code variation 2 of 12Related to a standard feature

Pythons in the cassette and Electron versions have a larger targetable area (120 x 120) than in all other versions (80 x 80).
