Player controller could use somme work, especially when you cannot jump... Cannot interrupt roll, cannot go under the stairs when rolling, controls are weird and sometimes don't feel natural (arrow key down + x to go down conflicts with roll that is forward + arrow key down...).
Otherwise the game is fun but very frustrating (no spawn points), therefore i decided to stop playing the game. Making a game harder is usually used when you don't have a lot of content and it isn't always a good solution, but keep it up!
