Very cool idea, just needs some refining (as jam games usually do).
Maybe start out with less obstacles and ramp it up over time. Also, the clutter makes it hard to know what's going on, and often i wouldn't even realize what the stroller hit. Try simplifying the rules a bit at least in the start (ex: the first obstacles are just gone once you blow them up, and later introduce a few that will bounce around, then slowly increase their numbers).
Good job, keep it up.
