I enjoyed playing through the game even though I wasn't able to finish it. I liked the overall artstyle and atmosphere of the game, especially the cute penguins.
Making the penguins follow you is a bit troublesome. It's better to leave them behind and later mass teleport them to you by shooting :P
I suppose I need to bring all the penguins to the blue spot but It does not seem to affect the counter. Is it a timer? Would be nice to have some indication of how many penguins there are left.
