For now, you can benefit from the "Milker of the Day" quest while actively 'stroking'. And that allows the schlongus to improve the stats without having to buy fertilizer. But I plan to not limit active play to just 'stroking'.
Oh I meant clicking and pulling up and down on the Schlongus without uprooting it, as opposed to just clicking to collect spore/increase energized modifier. Sorry for any confusion by my statement.
No worries. I think it was also due to my poor understanding (not a native English speaker). As for your suggestion, great suggestion! I'm thinking about it. This 'stroking' would of course fit the topic xD
