This is very fun, polished -having a team goes a long way!-, nice presentation, I like the main mechanic- it was very original and something other than "2 characters on a rope". The only nitpicking I suffered (and it could be me) is that sometimes the characters got "stuck" moving very slowly, and that wasn't great player feedback- I didn't know if it was me doing something wrong or "exploiting" climbing a high slope.
Other than that, I think this is one of the cutest jam games.
