A reminder your timer is starting to run out would have been real nice, as well as many other audio cues that I'm missing.
Gamplay is actually quite fun, and I like the concept, though there's a few things that feel against the design, like having to manually press a button 20 times to get the monkeys to open a crate. not good.
Its a bit hard to tell what is going on after you snowball sometimes, the expanding camera and increasing speed as you gather more monkeys does help with this though and by that point its not that crucial anyway.
Overall pretty good!
