Ah, I thought the yellow are would give me more fish or something. It's quite tricky to hit with the unstable webplayer. It took a bit, but I cleared the game. I gotta say, this is one of the jam games I just kept playing. It's a lot of simple systems but they allow for learning and mastery, How much time do I have left? Should I go for souls or fish? Which direction is the Knäkki coming from? I f I move forward and the music is not getting faster, it must be behind me. What's the best way to "feed" it without wasting fish? It's all things you can get the hang of.
Some suggestions: I think the yellow area for catching the soul pieces is just a tad too small. Similarly, the "feeding" area for the Knäkki feels slightly too small as well. Right now, it needs to be what feels like perfectly center. An optional visual indicator mimicking the music (maybe a pulsing orb?) to tell the distance to the Knäkki for us hearing impaired folks might be a nice addition. The biggest problem is that the systems aren't explained in the game, if not diegetic just a simple tutorial text is probably good enough.
Nevertheless, once I understood what to do this was a really addictive experience and I enjoyed playing it! Well done!
