Remove/change red/black scheme

[Krzysiu]

All color schemes are just visual except one, which changes difficulty. It's red normal fields/black axis/black death fields. In some cases it's hard to see the diff between axis and death field, like on the attached file. On my PC screen it looks rather ok, but on two smartphones both shades of black looks like a single color.

This has already been fixed, but a new release has to be made. That's all.

@Dariasteam can you please create a new release? This level is really impossible to play and really annoying.
