Divekick is based on a joke, that was turned into a simple game. People liked the idea of the joke, and the simple game became a much more complicated game and was given a $10 price tag.
Divekick is full of in-jokes and references that most casual gamers will miss. The game itself is somewhat tiring, limiting how often people are willing to play. Design-wise, balance appears to be handled through counter-picking rather than attempting to make all match-ups even. For a $10 game, it is fairly no frills. As a $10 game, it is overpriced.
NOTE: It is possible that Iron Galaxy Studios have abandoned this game. A 2014 update introduced an issue where the game crashes during Redacted's story mode, which has yet to be fixed as of May 23, 2015. The game's non-Steam forum, where a pinned Steam topic sends people with support issues, is overrun by spambots. A Steam post on December 25, 2014 acknowledges both the crash bug as well as the spam issue, stating that everyone was on vacation for the holidays, and that both issues would be looked at when they returned. Five months later, the crash bug remains and the non-Steam forums remain overrun by spambots.
