Suggestion: Text Bubbles! (Might be useful User Contents), Multitiple object Spawn (-_-), A Stable Joint (Making Cars, Houses is already difficult), On/Off Objects Break option (Did you remember the time you spawned a sword and it cut your master piece?)
Tip: If your new to this equip the conjurer and select the spells "Disintegrate" and "Time warp" It is very useful for bosses and enemies that revives.
Before suggesting read the freaking Description! Also before suggesting items CHECK IF ITS IN THE GAME ALREADY!! This should clear up spams from the comment section..
