This is well done. It starts out confusing, but intentionally so. First I was like - hang on, I can't go backwards and I was a bit against it because that's not what you expect from a platform puzzle type game. But I think it makes for an interesting design and puzzles so I definitely came around to it. I think it would be good to have the character stop just a little bit quicker after I release the key though - a couple of times I just slightly overshot where I wanted to stop and if you can go back on a regular game that's not noticeable but when you can't it's a little frustrating - nothing major though. The same with the going from one side of the screen to the other mechanic - at first it confused me as it's like walking into the abyss sometimes. But I also think that's intentionally so and I picked it up and liked it quite quickly. I didn't find any bugs. I did find a cat the meows nicely but I didn't stroke it as I don't know if it's had its vaccinations :)
