I think this is incredible, couldn't get past the level after the flappy bird level, was probably timing thins wrong but thats a fault on my part. I think the concept fits the jam perfectly and honestly could see myself sinking my teeth into a longer bigger better version. Potential ideas for your consideration if you do want to exapand, maybe some moving elements to the levels or maybe a button which can just kill your momentum completly allowing you to precisely stop and change direction could make for some interesting levels
