It's fine. It has all the expected charm I've come to expect from a Siactro game, and I had a good enough time with it.
But overall it's really not one of the finest games in Siactro's catalogue.

Visually it looks pretty great; the environments and character designs nail that Donkey Kong Country style the dev's going for... although I found the titular Beeny to be a little underanimated? It would have been nice if she at least blinked or something once in a while, otherwise I might as well have been controlling a beach ball. It's a minor point but just a little infuriating seeing as character design and animation is a highlight of the other Siactro games I've played, and yet that element feels a little phoned in here.

The gameplay is, however, pretty bland. I was kinda bored of it towards the end which is impressive considering its short length, and the incredibly samey level design and lack of consequence for failure made it a bit of a chore to get through at times. That being said, you unlock time trials after beating the main game, and these did help make it all a fair bit more engaging.

But yeah, overall, one of the weaker games in the Siactro collection I'm afraid...
