I thought about that and, if I will continue on that project, it will be like you have said, with the mouse wheel. There has to be more work on controls, to have the most intuitive experience.
Thanks for the comment
Nice job.
I had a similar idea, to create a gardening game, where player can grow and shape different plants and create garden of there dream. I hope, that I will some day create a VR gardening game. But for this jam I did only one aspect, shaping bonsai trees.
I would be glad to hear your comments on by game
