Nice game, I loved the ArtStyle and music is good

You should add some more levels 

The game feels too zoomed in. To fix this you can slow down the player, zoom out the camera or make place the camera a little ahead of the player when he is moving to one side or the other

Also, you can infinity jump and wall jump

finally, you allow player to go through platforms when gravity is upside down

overall, Good work

Feel free to check out my game :D

The game is too zoomed in and I feel like I am forced to make blind moves.  Its like having a race but blindfolding the participants and making them restart if they bump into something.

I liked the art.

pretty good. 

character walks against wall and still has walking animation.

and i didnt hear jump sounds.

Well done on your first game jam!

I really enjoyed the speed of the character, allowing me to try quickly again and again.

As @Toasted Gears mentioned, the invincibility of spikes could be implemented to help not dying. I suppose it allows for a few mistakes to happen.

Had a fun time playing!

Like

• No limit on gravity change
• Short levels

Dislike

• No invincible frames after getting spiked
• Unity's grey Background

I like the character, looks good! The idea and the implementation are great. One small bug I noticed is when you change the gravity, sometimes it moves too fast and might penetrate the platformer. Other than that, it's a lovely game!
