CHANGELOG

• Added enemies spawning visual effect.
• Renamed "life/lives" as "soldier/soldiers" everywhere (that reflects better the fact that there are multiple soldiers, each with a single life, rather than a single soldier with multiple lives).
• Tweaked some gameplay parameters:
  • increased maximum number of soldiers from 3 to 6;
  • reduced maximum enemies speed;
  • increased chances of soldier and weapon bonuses.
• Added 10 arenas (derived from the BOH mission "Wizard of Wor", based, in turn, on some Wizard of Wor dungeons).
• Reorganized arenas: arenas 5 and 10 of each stage are dungeon-like, whereas the others have a more open, geometrical layout.
• Made many internal improvements/extensions/bugfixes.
• Extended/improved/fixed manual.
