Update: I had a lot of fun and got to the end of all the levels (still need to work out how to get those last few coins!) once I worked out the controls. Thanks for a great time! I especially enjoyed level 7 and its animal trivia xD Well played with making the seagulls 'float' on water ;)

I was definitely reminded of Fireboy and Watergirl while playing through these levels. I think other commenters already brought up some of the weird physics (and in some levels, I'm not sure if you intended the giraffe to be unable to jump, like in level 2?), so instead I advise maybe adding a button so players can bring up a controls tutorial in the middle of gameplay. 

I really enjoyed the cute aesthetic and the clear collaboration between either two monkeys or the monkey and giraffe. Thanks for sharing!

Umm. I am sorry but I dont undestand what buttons, or intent on what I'm supposed to do to obtain the coins or how the doors/blocks function

The box does seem to get stuck in level 2. I couldn't retrieve the last 2 coins. Overall I like the creativity and 2 player implementation. Would have saved me a lot of trouble if I knew I could move the Giraffe lol. Honestly, would be great with a notification about being a 2 player game, some music, and SFX.
