There are two endings. Try listen to the water movement sound of the snake ( you can hear it clearly when standing still ) the audio is 3D directional so you can hear where the snake is, also rats can be used to distract it. The snake also patrols in the same pattern. Thanks!
Haha. Thanks for pushing through, It is definitely not the easiest game and with very little hand holding if any, plus a disorienting design by choice. Might do some little tweaks to make rats more useful or such in a little future update. Thanks for feedback and for playing, look forward to your playthrough!
