Thank you so much for checking out my game! I'll for sure rate yours, I'm just waiting for Itch to stop being so slow before I start doing ratings, lol.
As for difficulty - Yeah, I found in playtesting that if you focus on one tentacle at a time it becomes much easier. I tend to have one on each side of the screen and just switch between them to intercept ships coming from the other side. Maybe 1 tentacle would have been better - but it kinda didn't make sense to me to only have 1 since one of the things about Krakens is, well, they have a lot of tentacles, lol.
