Depending on how you look at it.
Firstly, as I understand it, the game is being created by one person, well, maybe two (and not a team of 200 people), for whom the game is not a job, but a hobby, spending part of their free time.
Secondly, creation requires certain knowledge (considering the quality with which the game is made. I don’t know about you, but personally I couldn’t do something like that). And I’ve seen games much worse than this one.
Taking these two points into account, we, as simple players (who received the game for FREE), can hardly show any dissatisfaction (don’t shoot the pianist, he plays as best he can). Any suggestions? Yes. Bug reports? Also yes. Wish lists? Maybe. Demand? No. Because it’s free. There are only two points here: take it/like it/play it or don’t like it/don’t take it/don’t play it.
I played what was there. I liked it. The rest is triviality.
But that’s my personal opinion, I don’t know what others think.
