This is a technical experiment/proof-of-concept - it is not intended to be a proper game, nor a polished demo. (Lots of rough edges, placeholder art, the note chart sucks, weak game mechanics, etc.)
As this app uses a few web technologies which are not available on all browsers or hardware platforms, your experience will vary, as follows:
It's likely that the code could be made to work on other browsers, but I've concentrated on targetting the iPad so far.
The video and tune are from the Windows 4k demo Elevated by RGBA and TBC, which (unsurprisingly) won its category at Breakpoint in 2009. There's a tech presentation about it here - I hasten to add, I don't have any connection with the geniuses who made that.
When the notes reach the yellow bar at the bottom of the screen, hit them, either by pressing on the touchscreen or using the keys C,V,B,N or M.
You hit 0% of the notes!
