Builds of the game for itch.io, Game Jolt, Newgrounds and GameDistribution: tutorial and games against the computer right away, no account needed.
Other changes
On itch.io, Game Jolt and Newgrounds the game now runs right on the portal: the tutorial starts at once, then games against the computer, without an account. Your wins stay on your device.
On Newgrounds the game asks once at the start whether it may send its anonymous usage count. If you say no, it plays fully offline.
On GameDistribution an ad may show when you start a game against the computer, never during the tutorial or a match.
The anonymous usage count now tells the game portals apart by name. It still contains no account, no device ID and nothing about you.
