This is probably a question that will come up.

The game will cost 4.99$.

It is a relatively short game, but has a huge "replayability" factor.
Since it is run focused and has permanent death, completing it once will take less than an hour, but the game has enough content (artifacts, monsters, procedural dungeons, unlocks, game modes) to keep it fresh for dozens of playthroughs.

I really believe it is a correct price point. It has a lot of fun stuff to keep you entertained for a while ;) .
