I played for 30-40 min i think. Made it to lv5.
Menu: I like everything. The only problem is knowing beforehand that A is the confirm button . Just put a note in a corner of the menu and you'll be fine .
Signposts: I discovered I had to press down by trial and error. Is not the end of the word, but or you add an "how to play" in the menu or you add a notification on the signs (like a simple blinking arrow)
Like Rezydent said, I had some problems with jump after a hook (playing with a pad), and from lv3 forward the success window for many jumps was so narrow that I had to smash jump after blindly hooking.
I enjoyed the game, but I have to join the choir "the game is very hard". Now, how much of it is intentional? Even level 4-5 are easy for you now? You have an hypothetical lv 20 of this learning curve?
Anyway, GJ. It already feels like a "real" game.
