I like idea 1 better but I have a few questions.
So like mono except you have to avoid all the blocks? A certain amount of hits and it's over? Sounds like an interesting idea but how do you judge score and such for the leaderboard?
It's the same, except if 10 or more people get a perfect run on a song, the leaderboard will have the same numbers over and over.
I don't know how different it would be from the other modes, your score when the song ends is the score that's recorded.
The idea is to make an avoid mini-game inside AS. Like the thousands there are on the internet, where you avoid rocks, squares, balls, spikes... But played with your own songs, with tracks made of them and with AS visual quality.
For the second type, it's like those collect-as-many-as-you-can mini-games.
Again, like the thousands there are on the internet, where you collect coins, candy, food...
Both are more relaxing than Mono(especially the second, where there's no penalties), the reason being having only one thing to worry about, avoid or collect.
It doesn't really matter if the kiwi would be the character(but it was the idea that struck me in the first place), just having these two mini-games would rock.
