The jump is weird, but the idea and the gameplay is quite amazing.
Graphics are very good, cool music, and it is quite fun.
The thing I don't understand is why you stop half a second the clock at the begining of each area. It is not needed.
Thanks for the comment! About jumping, can you give more details? Is it a problem with acceleration, animation or some kind of bug?
The timer stops when no enemies are coming, but your suggestion makes sense, we can change that in a next version after game jam feedbacks, thank you for the suggestion!
