I liked that it has a store and economy, and it's a solid base! Fun general graphics and sound as well.
The combat was a bit hard to get, e.g. I didn't quite get if it mattered where I attacked enemies from. If I cleared a room felt a bit random, but perhaps I didn't grasp the strategy - one enemy would hit me for 6 out of my initial 9 HP in one hit, so basically if they missed I cleared the room and otherwise I died.
