Thanks for playing, and for the feedback! I've never tried anything horror-based, but i'm glad that the first few moments of my monster fish showing up on-screen had the intended effect! Unfortunately in the last couple of hours its navigation wasn't working and my options for final coding were (1) Fix it so that it can navigate, but not attack, or (2) Have it constantly just attack the player with no complex movement. I decided that option 2 was more atmospheric, but looking forward to having full functionality for it!
And glad you liked the mechanic, I've never played Undertale, but might do so to get some inspiration for how to fine-tune my mechanic!
