I totally agree with you about the block placement confusion between the build phase and start phase, it could have been solved in a simple way. As for placing objects in the wrong spots, you can replace any misplaced or changed object with the default tile, which gives your cookies back. The trap ratios are shown in the info box at the top right next to the tiles, and yes, in some cases you can place extra traps just to meet the quota—it works kind of like cookies in exchange for your moves. Overall, I really appreciate your feedback. I especially value comments that point out the flaws, because it shows you didn’t just play the game casually and it helps me improve myself. Thank you!
