Really fun playtrough! The art is looking good and the only small complaint that I have are maybe the clouds which are a tad bit too obvious. I started dodging them at the start :)
I must say that this is one of the few games I really enjoyed playing! All the small thing like the eyes moving to your mouse pointer, add up to make an amazing small game!
Love your idea! Especially the minimap makes a nice addition to the game. Only thing is that I had some performance issues but other than that good job!
Really fun game! The art looks wonderful and I really like the tension that builds up when you go deeper. Other than maybe a wider variety of upgrades or smoother movement (you swam faster when going diagonal) the game was very interesting and enjoyable to play!
