It was a very nice little story! The idea of the bet between the two gods was a very nice framing device for the events, the dialogue was entertaining and the descriptions great.
Although I feel like the game doesn't make as much use of the medium as it could. The basic Ren'py gui is fine, it doesn't take away from the overall enjoyment, but the way descriptives and dialogues appear and are paced does, feeling more like a standard Novel than a Visual one.
The art-style is great, at times even evocative, but there's some imprecisions when displaying different sprites of the same character (some PNGs are taller than the other, or smaller with a different level of zoom...). And other people already have commented on the issues with the loudness of the music, I will add that when they start looping back they're very noticeable.
Overall, a very solid entry!
