Thanks for the feedback.
I think most of the issues you mention come from not reading the bits of tutorial the game tells you (and therefore, not discovering right clicking for tooltips). I tried to minimize the required amount of reading, but the game concept (as well as what each tile or character does) is too difficult to convey without text.
Regarding 'very few animations', what you think should be animated? I am not an artist, so this is difficult for me.
Hmm I am cannot claim to be that experienced with game polish myself, but some easy animations to make it less static could be doing a squish to the character (i.e. squishing down the character sprite and then restoring the scale again over the course of a few seconds) basically a cheap idle animation. The goal could have some sparkles or something to make sure the player knows that is the goal. Also I would reference winning animations for puzzle games that have a similar "three star" system - they make it feel awesome after every success (usually I see a separate screen for winning for example).
