“Multiplayer games on Switch have really just about become a challenge for me to review in many regards...”
“Swimsanity! has a great idea of movement, which fits very well in an underwater themed twin stick shooter. However, not making Adventure Mode more accessible to a single player is something I missed. Playing Swimsanity! alone - besides being extremely difficult and frustrating - it is not as fun as with friends. Its graphics and soundtrack are pleasant, with underwater effects that are suitable for a game of the genre. Although it is a somewhat simple experience, there is enough content to not be characterized as a castaway.”
“A full-featured multiplayer effort, Swimsanity! excels in its frantic competitive gameplay, with a co-op experience that we found critically lacking in enjoyment. Skip the adventure mode and dive straight into Orb Rush with three friends for a good, fun time. The package holds together well despite some blandness to the visuals, and there's certainly plenty to do if it gets its (fish) hooks into you. Swimsanity! holds up well in a crowded market and we truly hope to see it succeed.”
“With roughly eight modes to choose from, Swimsanity can be a blast to play with a group of friends. It's just unfortunate that it never reaches its full potential due to bland visuals, unbalanced difficulty and lackluster single-player options. Nonetheless, it should still have some appeal to anyone who's even remotely a fan of the genre.”
“Swimsanity! offers a fun blast of online or local versus play. Its game modes aren't terribly original, but they work well in the underwater setting. Unfortunately, the fun doesn't carry over to the game's adventure mode or the single-player options.”
