I like level 4 quite a lot more than the other demo level's I've tried. However, I still hold many nitpicks about the game, and I don't feel that it approaches the same level as Open Hexagon.
The difficulty factors aren't the most enjoyable. A slow cursor combined with slow, clumped walls does not bring me joy to play. Inverting controls is even more frustrating, but I support the decision to add more non-conventional ways to make it challenging
There's a lack of graphical options and functionality. When in the menu's, my GPU usage will instantly spike to 95%+ load (unnecessarily heating it up, and my GPU isn't a bad one), although it's less bad when you play a level.
I'm not a fan of how it looks either. The color of the shape's border in the middle is different than the cursor/walls, and the cursor is too close to the shape. However, this doesn't matter at all. I still plan on playing this game a lot once it releases on steam.
