Source Gaming - 5/5
For 500 YEN, this is an absolute steal. The game doesn't offer that much, but its low entry point makes it a great in-between title. It's fun and has quite a bit of charm. The game has its issues, but nothing that makes 500 YEN less of a bargain. I would strongly encourage players to pick this up if they have the extra cash laying around.
Nintendo Life - 9/10
Stunningly stylish and with an irresistibly kinetic sense of motion, Kamiko is a true gem. It's a quick ride, to be sure, but gorgeous pixel-art visuals, a lush soundtrack and three very different characters with plenty of speedrunning potential make it well worth coming back to. A uniquely appealing, action-packed package for less than the price of a prayer plaque, this is an easy recommendation for any Switch owner.
Switch Player - 88/100
A charming little game that melds action and puzzle elements together quite nicely, Kamiko is a pleasure to play and experience. It doesn't last too long, and some of the enemies are rather easy to dispatch - but the different characters and their unique weapons make it a good game to replay, and the speedrun elements add to the fun. Overall it's a great way to spend a few hours, and that cheap launch price definitely doesn't hurt its value any.
Destructoid - 8/10
I absolutely love the colorful art style that makes up the set pieces that themselves tell a story of a forgotten post-apocalyptic world, and the soundtrack is composed of retro-inspired chiptunes.
Nintendo World Report - 8/10
If you are looking for a quick game, KAMIKO will absolutely serve will you well. It has all the markings of a great game with entertaining gameplay, sharp visuals and a solid flow. I had fun replaying the four stages and seeing how I could improve over time. That being said, I can easily admit that the game is super short and the levels won't change on future playthroughs. If you have seen the content once, you will know the game inside out. That might a sticking point for some, but the various characters do make it worth your while.
IGN Japan - 8/10

Tired Old Hack - no score, positive
If you don't fancy messing around with foreign eShops then (and if you do here's my guide showing you how to do it), be sure to give Kamiko a go when it finally reaches western shores. It's cheap, it's charming and it's ideal if you've got an hour or two to kill.
