I had a similar idea of a platformer where you control the level, if you want to play it.
I thought your game was too boring (may seem harsh but it's the truth) as it lacked meaninful interactions and some speed. Keep making games and always think how would the player feel playing it. Its pretty hard to make a complete game in 48 hours, specially if you are a beginner, so the fact that you got it release within the timeline is an achievment nonetheless
