Similar background as my project, with a different approach and mechanics. I love your game an the proposal, it´s fantastic and I could play a lot (I´ve escaped)!
Feedback (in my opinion):
-
Why, why there are no SFX and music? The game would be more fun with 10 minutes to add only a loopeable theme and a couple of effects…
-
The mechanics could be better, IMO, changing adjusting the gravity on player, so the character could “surf” the falling objects in its ascendance… ;P
-
Also, a score (meters climbed, time… anything).
In resume, congratulations, it´s nearly a lot of addictive, hehe.
