I'm not much of a sokoban player, so these puzzles might have been simple, but they happened to be challenging enough for me, especially when put under a time limit. And actually 20 seconds felt a bit too short. Only made it to maybe Thursday of Week One. Playing like three or four runs total.
It seems I've come down with Ludominimus Nintendosis, or Nintendo Minigame Brain, because all I can see is how tiny games can be perfectly shoved into larger games to introduce moments of extreme novelty. This being a great example. A game you can pick up fairly quickly, exhaust fairly quickly, and then move on back to the main game satisfied.
I love the aesthetic. I can really imagine the salarymen and women ripping me limb from limb after making them late to work. With, of course, the reward for successfully doing such an important job under so much pressure is to be allowed to wake up another day and do it again!
It feels like a lot of puzzle systems don't like being procedurally generated. Handcrafting seems the way to go. But it is certainly interesting to try and see what can happen! (Perhaps I'm out of the so called loop and there are great generated puzzle games out there? Tetris? But that is a different style, or what not, of puzzle games, yeah?) Anyways...
Had fun. Keep up the great work!
