Fun game which explored a lot of different themes and had a wide span of mechanics which was fun to explore! I liked that the character was very snappy and fun to control although the control scheme was a bit unconventional and pairing WASD & P with the mouse meant I had to shift from having both hands on the keyboard to one on the mouse quite frequent.
Love that you chose to freeze gravity when using the slingshot, it made it quite useful! (Although the slingshot allowed me to ignore some obstacles and fly straight though spikes :P ).
Having instant restarts was a smart choice but I would have liked some checkpoints.
All in all the game was fun and had a high skill floor which was frustrating but rewarding to get though. Great work! Keep it up :)
