Pretty neat, i like the sorta speedrun vibe you get from the game since you have to not only beat the level but beat it on time, i like the puzzle element in it with the alternate routes, keys to pick up to unlock some routes etc... 

Sadly i didn't go very far, i got stuck on the 2nd level with the baby, cause i couldnt figure out where i could pass when reaching the spiky blocks near the end, and i can't seem to grab the second key without being stuck, spikes block the way and i can't jump high enough to go back up :(

Other than that the game feels solid, especially if it's a first.

So i'd say level design aside you did good :)

The game was amazing. The art, music and SFX was a good choice.

But I was wishing that the levels changes, not the same one with another challenge (Which was a clever idea by the way). And one small bug, that the music doesn't loop, it stops after a while.

Overall the game was enjoyable. Nice job!
