I like the icebreaker exploration theme; it's quite unusual. The implementation of the theme is very intuitive.
With the exception of one time when I couldn't get the game started (all the buttons on the opening screen had no labels, and didn't work), I didn't notice any bugs; the game seems to work quite smoothly.
The graphics are serviceable to get across the overall appearance of an icy sea. The sound effects are a little weird.
What I think would really elevate this project is more granular detail about what exactly goes on during those encounters. And I don't just mean flavor text, but some associated variety of challenges to the player. Minigames perhaps? Smaller-scale simulations?
