Fun take on the theme, I like it! I got a score of 294. Would be cool to see some new types of prehistoric beasts that come at you, maybe ones that move around more or do something unique. Overall fun and creative game, good job!

Good job with the atmosphere! Like some others have mentioned, I was able to avoid the obstacles by staying at the bottom

It took me quite a while to figure out what was going on due to darkness and unusual perspective, but once I did, I had a decent time. I enjoyed the artwork and i love the flappy tail thingie on the player character!

Interesting idea, I like how creepy the sea creatures are! However, the gameplay wasn't very challenging as I could just sit at the bottom and not get hit; I'm assuming that was an oversight and will be fixed in the next update. Great work for doing this in one day!

Cool idea but I was able to just sit and not press any buttons and keep my score going. There didn't seem to be any obstacles spawning on the lowest level. 

love the super freaky art in this one!

i'm not sure but I can get world record without moving and I feel like this game have a lot of ideas but 4 days was not enough

keep going!!

edit:

I didn't know I can fly ye that was cool but the player must die if he touch the ground but ye nice game

really good vibes in this one! very simple, but I had some fun playing! :D

really nice atmosphere, and the art is great The game is obviously very simple, but I could imagine an evolution -like system where  you climb higher and higher through different kinds of creatures.
