I quite like the point n click gameplay here, but I think the "Rocks=death" thing is bad idea... maybe it could be a chasm or lava, but killing the player for touching the wall is not a good game mechanic.
Also this:
This is not fun for a player to look at. I don't think you need to tell the player everything all at once.
Most players enjoy figuring things out for themselves.
Anyway, sorry for the negatives. I wish you all the best for your game and future games
