Having to shrink the octopus to free up space to explore is a fun concept, and I found the tank controls combined with slippery edges and moving platforms made for a nice challenge
Collision detection for the hazards seemed a little unclear and unforgiving to me, although still managed to beat a few stages :)
I also didn't realise the game was slightly larger than my display so couldn't always see where I was supposed to go - that's definitely on me though!
