List of Cons First:
The game is poorly optimized when it comes to tabbing over to other tasks and tries to appear invisible on the desktop taskbar unless you specifically alt+tab over back to the game
The game also operates controls if you decide to run it while multitasking with alt+tab,
The worst thing this game has done was delete my local save data after it slowly went into my settings while i was in other tabs.
The Pros Now:
Luckily The game has online features such as making an online account with The Puzzle Club and linking your steam account to it, this feature has saved 52 of my puzzles from being absolutely completely destroyed, and as of the time writing this, 12,121 puzzle pieces placed, 347 hints owned and 40 hints used.
all of my puzzles now appear in game as such:
A Few Examples would be:
zero/640 university with completed puzzle badge
zero/455 lake with completed puzzle badge
zero/840 painting with completed puzzle badge
These 3 puzzles for example count as completed and count towards achievements with the badges still appearing on them.
However: any halfway done or partially done puzzles have bounced back to absolute zero with no completion towards them whatsoever. meaning i have to put at least twice the effort in to complete them.
In Conclusion: The games great regardless of what negative reviews say, So i say to the positive reviewers, DO NOT RELY ON LOCAL SAVE DATA. you will regret not making a puzzle club account and backing up your data to more than just local data.
