Hi, happy to be your 20th rater! :) I love the graphics and how you managed to integrate the assets seamlessly with the gameplay. The background music was fitting the atmosphere nicely, and voiceovers are always a nice addition, especially for games with a heavy narrative like yours.
My only issue was with the controls, I've not yet played a game where WASD was fitting nicely with an isometric view, I always have to push boxes into directions that require two keys. Pulling a box was even more confusing, I got stuck many times.
The built-in tutorial was implemented well, it was useful yet it wasn't intrusive and did not break the flow at all.
Overall, a great job, way to go!
