We are not all seeking the same kind of review in this kind of Jam, the wish of the developer to "improve the game" can be the strong. Me, I really in the full polishing phase of the Game and i am in the phase where having the players feeling or advices can be very useful especially the "too honest" reviews. Even if i will certainly make choices that are in adequation with my tastes and my vision of the game.
It's maybe why he/her can seems a little too harsh.
I will retry your game later i only made a quick test: I really like the ideas and the concepts and the graphisms especially the kind of god power when you can move and through objects (good implementation). As beginner developer Pathfinding is not the easiest thing to set up, I struggle too (In a none published game yet but published really soon). Your prototype have the essential we can see what you want to do and it seems cool. As I said i will give it a retry, i probably missed something.
