It really could have used a map, but over all it's not an extremely complex labyrinth, i never felt like i was lost, but maybe i'm just good with mazes. There are just like 2-3 winding paths, the rest is dead ends that are easy to remember, it feels bigger than it actually is.
The combat is not actually annoying because you can just double jump past most stuff, you can run past the green enemies taking a couple hits, and there is pretty much no penalty for being defeated. It's that fine line between hard and unfair. If you want to play it to prove something, you can actually learn to time your attacks to the enemies animations and never use your gun or get hit, but if you don't want to, the game doesn't force you to. At the very least i never felt like i was being hindered by weird hitboxes or mean spirited artifial difficulty. I can apreciate at least that.
CG is pretty good and the main character is hot. I would have liked it if the animations where in the same style as the crawl/climb ones instead of the Playshapes' rig thing it's using, but over all the art direction is solid. There's also some funny lines if you can read them.
Overall i'd say it's fair enough, didn't mind wasting a couple hours on it.
Edit
The animations might seem clunky, but they are consistent in it, it's easy to get used to. Enemies do have wind up frames to their attacks instead of being instant hits. The hitboxes are well made enough that you can consistently hit something before it can hit you with good timing. It's nothing special, but there are so many small details that make it much better than it actually looks like. It's playable.
