Hey, first thank you for playing and writing this feedback!
Glad you liked the general experience. You are 100% right with the content. It is still in very early stages and I plan to add much more content to it, so there will be more depth to it. Right now, if you play it very efficiently, you are done with it in 15mins, which is obviously way too short :D
I have various ideas, but it takes time. My plan is to have the next patch finished around end of February, so hopefully to see you around for that and looking forward to your feedback :)
