I really like the way you introduced horror elements in a seemingly common 2000' aesthestic and gameplay theme. Visualy your transitions from level to level are smooth enough to really get the sense of going down through the deep waters bits by bits. The music fits well with the visuals and the era it's evoking. The experience feels complete and coherent, i'm pretty impressed with the level of polish you managed to achieve.
The money//collect curve around the end of the game feels a bit stiff though aha :)
Thanks for this experience !
