A truly incredible concept and style. I love this idea; it feels novel and I just really enjoyed it. Also with the voice acting, the humour, and the little bits of investigation -- very impressive. (It feels like there's a lot of potential here for a larger scope kind of situation, but I digress.)
I'd say the weakest part of the game is the putting down of the chess pieces and trying to get them to go where you want them to be. Clicking to mark the locations feels like it would have been better? Also, I was confused about what the "security" piece was for until I saw the solution -- I thought the "boss" looked like a security guy, and just pinned that on him. I also didn't see where the van was at first and ran out of time. I.e. the onboarding and information shown could probably do with a little bit of extra care?
I also liked that you got points for how close the positioning is, rather than just needing to be perfectly on target. It made it feel very doable despite the difficulty.
Also, for this next part, you should know that I'm not overly fond of games with time limits, so take what I say with that in mind. I didn't like that the marking of the parts was part of the time; it feels like it would have been more fun(?) to have the scoping out be time limited, and then you have to place things until you're happy and "submit". And even further, I'm wondering if it would be more interesting to have the scoping out and marking be entirely separate. I eventually got into a strat of marking bits at a time, while the fantasy of scoping out a place feels like it would be more separated. E.g. having a lot of time to walk around and memorise, and then when you think you're ready, you leave, go to the hide-out, and then have to reconstruct it there. (But again, maybe that's just my hatred of timers.)
Really just a great game. Really, really well done. I hope this does very well.
(Also, I don't know if it was just me, but I got a drift on the X axis viewing when the game was controller my cursor (but not when it wasn't).)
