nice game, the repetitive obstacle made it a bit less, after taking 3 death in programmer level all obstacle where learned. and fairly easy to overcome. the art was very simplistic but nice, also very consistent art. overal level design where nice but having more consistent difficulty curve would be a great improvement. perhaps a difficulty setting to make it slightly more difficult would be a nice extra if you continue working on it, levels were extremely easy except for programmer one which felt like a good baseline difficulty. as for the character jump you might want to take a look at better jumping tutorial atleast for the increased gravity on falling downward as the jump felt a bit floaty. all in all a good game, keep up the work
