For what is in the end, a top down "puzzler" based on trial and error, i liked it. Its a good size for a two day game jam and fits the chosen theme well. The visuals are great and that you could choose to get the full context of the game before playing as well as the "story" etc. was nice extra touch and makes the game feel more "complete" (even if the text itself was a bit lengthy, also no fan of a pure text tutorial).
I don't have much to say about the game-play, its extremely basic. However I think you made the right choice using trail and error as the main challenge, as adding extra complexity could have easily take way to much time and becomes difficult to explain in a small game. However, I would have loved to se the challenge focus more on conflict of space of the ghost and the character, what do you need to press in what order to also not have the ghost in the way? etc. Kind of like those classic box pushing challenges. Also would have loved another level or two.
