It's not bad. I solved it, but I had to brute force part of the safe, as I only found clues to the second and third symbols. Anyway, you might get criticized for the hand-drawn art, but it's fine as it is, and the distant submarine effect in the background is fitting, just eerie enough. It's nice that some of the environment is interactive, but some of it will probably become a red herring for certain players. Lastly, I usually don't usually like escape games with time limits, but I guess we have enough time to do everything, although fiddling with the last puzzle take a while.
Worth noting that we can hold down the left mouse button to speed up the opening text.
MINOR SPOILERS:
There is a very pixelly spot on the painting, and I almost missed it completely. Make sure we don't have to click all over the place just to find the right spot.
The word puzzle is very clever, and I appreciate what you did, but the clue is a bit confused. It took me a while to figure what to do with multiple instance of a letter, especially since "A" appears more than once in Master K. Dylan, but the others letters do not. It took some time to find the exact formula.
Solid work for an early game. I'm curious to see what you do next.
