Thanks for the feedback. I can change the key "E" to mouse-click to continue logues :)
I'll add the story and tutorial part after this game jam's voting period is over.
Did you read this on the game page:
"Mouse left-click on items -> start monologue.
E -> continue during monologue and dialogue. exit logues when it is done.
Space -> start thought monologue.
Mouse right-click -> combine one item with another item. (there is no inventory, so combine two items directly during gameplay)"
The player should combine items with mouse right-click until something will appear :) And then the end cutscene will appear, but this part is not perfectly implemented. I hope my answer did clarify on how you do proceed in the game?
