This is a good game i like it. it's really fun! the graphics, audio, and even gameplay is nice, good job! so, here's some cons i found in the game: there's no music, the level is small in height and when you get deeper there's not as much oxygen bubble but i think that's how you intended it to be, but also the tridents are harder to see, and one more thing when i downloaded it i had to download both files and put them in a folder  so i recommend you first put them in a folder and zip that folder, then you can upload the folder to itch.io, but overall nice game.
