Nice idea! I really liked the controls in this game, especially the dash - it felt good to dash towards an item when it was in my sights (and it's definitely something I woukd do in real life haha!). I liked that you couldn't dash if you were holding an item, that added a bit of tension to the game.
The layout of the area and items is very balanced - the spread of items didn't make the game too easy or too hard. It would be cool if the items were randomly placed every time you started a new game.
One thing I found difficult was determining which parts of the scenery I could walk over and whick parts I couldn't walk over. Maybe an outline on 'solid' objects could help. Also, I couldn't hear any audio - not sure if this was intentional.
