What a lovely little game so far :) The grappling hook could need some polish to make it easier to control. I like the feature where pressing space bar allows you to maintain velocity and stay in the air for a bit but it's a bit hard to tell when you can still press the space bar.I feel like a visual indicator like a bubble around the grappling hook telling you the area you have to enter to make the grapple hook retreat on its own would be nice. Just a suggestion, of course. It's also a bit weird how you immediately plummet to the floor when you hit a wall.
But enough with the negatives. Now's the part where I gush about how cute your art and characters are and how nice of a concept this is :) It's looking really cute so far so I can't wait for what else you'll do with the art style. Unfortunately I couldn't get a good look at the fine print on the baked beans, though :V Anyways, it's looking very nice so far and I see soo much potential in this and I'd love to see where you're going with this.
Only cool people can read this sentence.
