More interactions are indeed among things I plan to add, but I can't promise I'll have time to do it before game is 1.0.
I plan to first polish the game more, and make the gameplay loop cleaner and more enjoyable in the main level. For instance stuffing the thief will be more rewarding and she'll drop powder when you jump on her :)
A new rare variant of golems will also be added, harder to catch but higher reward !
