Mixed feelings here... this game and the concept in general is FUN! But unfortunately quite buggy. I tried 5-6 times (that's a lot compared to other games) but the thing that ruined it for me, is that the game loop is busted. You can't restart the game after losing, the retry / continue buttons don't work, even if you try getaway. I had to close and start the game from scratch. Also... might want to explain what a "tumbler" is to us non-burglar types haha. I couldn't tell what I was doing wrong exactly. The keyboard presses are not as delicate to do a good job. But after managing a store lock, the case lock inside triggered the alarm immediately, I didn't even do anything.
This can be a super fun game, and in fact, a great multiplayer game, where you play with a teammate accomplice and you have to coordinate delicate moves, or perhaps another entire team of players are the cops etc. I liked a LOT about this game, but unfortunately a bit buggy, and perhaps the difficulty level with how delicate those lockpick moves are could be toned down. I would suggest fixing the game loop bug and I'd happily try it again.
