It's a little annoying that you can only see how much something costs or how much it generates because of the scrolling words like "Buy!" or "Squeezing!". Also, it's a little counter productive to hide the "Cash on Hand" when opening the Upgrade/Store menu.
I personally wished there were more levels like the ending of level 10. It was frustratingly enjoyable. Little things though. If you "R" to restart before you die, you die immediately as you spawn. Some levels also had pretty large shortcuts which I don't think were intentional. Otherwise really fun game once you figure out what to step on and what to avoid.
I think the precision problem way be solved by allowing motion in all at least two dimensions at a time. instead of locking motion in just the one you moved first. Then you'd be able to "wiggle" the shapes around to fit better, instead of shifting up down, left right, forward and back, until you find the right combination. This might possibly cause other problems, but I think it would solve the precision problem everyone seems to be having.
Very fun concept. Great game to use the mouse movement scheme. It does get hard to control the whale when its at +1,500 HP though, a deeper ocean would be nice, with bigger prey. Maybe giant squid that you have to "fight" somehow? Upgrades would be a nice idea, but the whale gets stronger ANYWAY as it grows so they wouldn't be necessary. Upgrades might just make it so you're near invincible when they get maxed out like most games do. Different maps or maybe even a story mode where you get to fight bosses like Captain Ahab or some famous Pirates. 4/5
Only thing that bugs me is the money system, when you start picking up a lot it kinda leaves a long white trail behind you that blocks your vision, maybe a different color coin to symbolize a bigger amount instead of a screen full of white circles? Other than that nice game.
OMG LEARN TO CUSTOMIZE COLORS LIKE THE GAME ALLOWS YOU TOO!@#!@%!#%!#$!... idiot... Good Stuff, I suck at 2x2 and 4x4 tho :/ I can get all the odd dimensions easily tho.
