It was fun but a little confusing.
The overworld could use more sound design. The battles had nice music and a decent interface.
But because of the speed clicking glitch I got the idea that's how I was supposed to be playing it.
And I had no idea the item just before the Boss was the Time Reaver.
I thought maybe that was the name of the enemies and I was collecting their corpses.
But after I read Crypt Rat's review, it became clear what I was doing wrong.
Very impressive first swing at a game.

Here's my playthrough: Cosmic Caveman Pt1 by Kenny
As a side note, I liked how you picked things up by looking at them from an adjacent square. It felt weird at first, but I got into the habit of spinning around to suck everything up,! XD
