Bizarre little game with quite an unusual concept. It seemed to want to be quite poignant, with two figures looking out at each other across a misty sea, but then suddenly you have to do quite complicated mental arithmetic problems in about two seconds in your head. These two things do not seem to fit together, but that's part of what makes this interesting! However, as everyone has noted, it is way too hard, especially since you're basically hoping that you not only get easy equations but short ones. Once you've solved two or three of them, getting a long equation then almost certainly means death, because solving 5-9+7×6-2×8 in two seconds is really difficult, plus the long equation is certain to hit your boat. I really like how the increase in difficulty isn't arbitrary, though; longer equations aren't just threatening because they're harder but because they're more likely to reach the boat and sink it! And you can always, if you want to, give up some of the progress you've made to start again. There are quite a few very clever game design features here, even though it seems like a simple game of hard maths, and I would like to see what the author does with a game with a bit more scope for creativity.

It's alright but the difficulty spike is random as I got some massive monsters very early into the game. Would work as a minigame if that got fixed. -@h

Very enjoyable but my arithmetic is not nearly good enough.
