Thank you for the detailed feedback! I agree with everything you're saying and do need to improve on these.
There are different minimise size options in the options, but I do need to make it resizable the dragging, this will allow the user to create any size.
I'm not too worried about people cheating the system, but hopefully I'll add a limit so it makes it a bit more tedious to cheat the system. Currently it is stupidly easy to do so.
There will be some 'interactive blocks' but that will result in some animations for the Study Buddy, which the cauldron is a test version of that. None that the player will actively interact with though.
So many things to add to the next sprint :)
My next sprint is to improve the productivity tools and minimised versions to make it more obvious when things are completed.
And also add some kind of red dot over the build icon when mana is full so the player is reminded to place 5 more blocks as their 5 minute rest break in the pomodoro cycle.
