You can right click to touch things!
There's a few more interactions too, so take your time! Also, you technically don't have to do all the quests to finish (only the last one)
So I finally done the last quest and done with the game! The choice of no bgm and only se really adds to the strangeness and minimalist of a place that is essentially a white void. Mentioned this before but i really adored all of the doodles! Especially the more abstract and creepy ones (also imagine my surprised seeing one when wandering the white space lol).
Anyway, this is a simple game but i love it! Great work!
