Not a fan. The level design is just tedious and repetitive without being challenging. I Just finished level 3 and just overly convoluted and easy.
I pressed space a dozen times before I realized I was supposed to hold it down. "To speed up time, hold the restart button" is a terrible idea: why not just use a different button, why make us stand still to use it, why not just make it happen in a timely fashion by default?
I went and played a handful of your games and they are all jam games or games made in very short timeframes. Your rapid prototyping skills are great, so I recommend spending time adding polish to a game rather than trying to get it playable as fast as possible. Often times I'll get core functionality working in an afternoon and spend weeks tweeking the paramters until it feels right.
