For those who complain about 1000 note streak achievement being too hard - it's nothing compared to the third secret song itself.
I have no trouble getting perfect on "I Just Wanna Burn" and I can barely get gold on the final challenge.
So practice more, my friends, there's no easy way. You'll see improvement, some day, regular songs won't be a problem for you, even on pro... and then you'll be ready to face the ultimate challenge. Good luck.
It was a great idea for a game, but execution sucks.
Map generator needs to be fixed, in 1h of gameplay I've already experienced a box-like situation (lakes around the portal).
Some things are too RNG dependant.
It sucks to have to restart a run for hard badge over and over again because of shitty quest choices (four not-worth-to-do quests). If at least 4 quest of different ratings were provided, game would be instantly much better.
Similar goes to levelup rng. Pure random is extremely salt enducing and really can destroy someone's plan.
Beside that I found some bugs during my short gameplay. Apart from popular complain that characters often get stuck (which I don't really mind, since I find this an additional challenge rather than bug, since it's easy to say when you or your opponent will get stuck), I observed that sometimes game sends me on a different quest than I picked up, which is extremely annoying.
For those who (like me) perfected all songs without a problem, here's the challenge: perfect all songs using only one finger from each hand. I'm trying that (for now having 5 perfects , 8 golds and silver on Train Wreck - this one is hard in this mode) and having a lot of fun.
Achieving two-fingers full perfect seems possible. Only Train Wreck is very hard due to frequent double hold notes, I think I will perfect all other songs that way soon.
That was hard. I had to use walkthrough to get a hint for two puzzles (and two other solved by checking all the cases)... without this I'd be stuck in this room for many hours...
