Well, the whole puzzle is about fully understanding the battle's system. I hope you'll like it.

I'll try your game in the mean time.

Hi there. Anyone wants to play and rate mine? I'll play and rate yours. 😊

Mine is a puzzle platformer... but with only 1 platform. (🤔 Can you even imagine that?) https://itch.io/jam/gmtk-2019/rate/463952 

If you want some real good out-of-the box thinking puzzle. So far only 1 of the 11 people who rated it managed to solve it (afaik). It's an in-browser puzzle platformer game. The art is really simplistic, as I focused more on quality of controls and level design.

I would've rated yours, but I don't have windows on my pc.

Omg your game looks amazing, I can't wait to try it out! We made a puzzle game called Einnsámr: The Lone Warrior, check it out here: https://itch.io/jam/gmtk-2019/rate/463168

Hi. I am going to play/rate your game. Hopes rate for mine as well. Appreciate. (•̀ᴗ•́) و ̑̑

I made a puzzle game myself and am wanting some ratings! You are given a series of puzzles and you have to solve each in only one move, and solve as many as you can in only one minute. I'd love it if you could check it out and I'm looking forward to playing and rating the other games in this thread! :) https://itch.io/jam/gmtk-2019/rate/460707

This is our game!

A dungeon crawler where you can only recruit one member at a time! 

Rate for a rate!
