Hi! I would give more detailed feedback, but I think I'm missing something? I cannot access any keys, because the only one I see is behind a locked door. Can you explain what I should do so I may proceed?
If you go in the bottom right of the first level there is two white case. If you step on them you get transport into another room where there is the key for the prison cell.
I really like where this is going. Awesome polish on the movement and general level design for the time allotted. It would be cool to be able to queue movement commands as a movement is in progress, makes the game a bit more accessible.
