• result is random, but won't ever find same result twice.
• battle benefits are always higher than search costs by a factor of M.
• exit ($0), search again ($N)

• before battle: both positive and negative trophy numbers are calculated for each player.
• before battle: a percentage of both elixir and gold is taken from each player into a deposit.
• during battle: attacking units are never returned back. once deployed they're lost forever.

• lack of world map

"I hate paying for speed ups. I much prefer purchasing non-consumable content
that enhances the game or unlocks new abilities." - Ryan Hoover

"I agree with you on the too steep progression of the production timers. In
Kabam's games you go from seconds to minutes and from minutes to tens of
minutes, then hour, a couple of hours etc. In Clash of Clans they jump from tens
of minutes to several hours and then quickly to several days. And it really
kills the fun and I bet some retention too.

Nevertheless these are a matter of tweaking and content. When you launch a game
you're forced to have long timers and a lot of waiting/grinding simply because
you don't have enough of content to last. But once you get few updates in and
add that content you can simply reduce the timers and hopefully see increase in
retentions." - Michail Katkoff
