That was cool. I really like the gravity flip mechanic. I think if you leaned into that even further it would be super fun.
The one thing I found frustrating was the sluggishness of the astronaut - which makes sense if he's on the moon, but i think it would be more fun to control if he had a little more agility and gravity was a little stronger.
Great sound effects and great character animation. The walk cycle was super cool for the player character.
Great game overall!
