Giving kudos for setting out your game in such a way that it can be played on mobile! Something I should have done myself, simple but useful.
It would be nice to see a scoring system, maybe with some pick ups for bonus points, something to bring out a risk/reward element.
Overall though, I had a good time with it. I like that the character constantly moves so you can't survive just be making little nudges, that was definitely a good decision!
