What players say

Players praise the realistic water physics and find the core puzzle gameplay relaxing and fun, but the early access campaign is short at about 8-10 hours. Performance issues on Steam Deck are common and the price feels high for the current amount of content. The comedic narrator is a highlight, and players are eager for more levels and tools.
