When I first saw the game title, I thought it's gonna be about XIV century Slavic pirates xD Just out of interest: is there any specific reason why you named this game "Vyatka story"?
Gameplay wise, I really miss the opportunity to control my slimes like in RTS games. Without external supervision these little fellas tend to get stuck. On the first level, many of them tried to attack the top left corner of the map, even though there was nothing. Or did I misunderstand the controls in some way?
Also, attacking with F key is a bit counterintuitive. I'd appreciate to have an opportunity to use mouse for that.
Other than that, if Itch.io is not lying and that's actually your first game, that's a good start!
