-It's obvious what it's supposed to be if you've ever played a game before, but the "ESC" on the controls explanation is completely unintelligible.
-It doesn't tell you what the interact button is.
-I don't like the way the skeletons seemingly randomly change to their attack sprite and start doing contact damage. Enemy behavior should be mostly predictable. Maybe decrease their normal movement speed and add a short wind-up before they lunge at you to separate their idle and attack states more clearly.
-Enemies in general don't pose much of a threat apart from their erratic movement and lack of movement noises making it hard to keep track of them.
-Needs straferunning.
-The first Pacman level is way too easy, while the second one has so many enemies you literally can't move.
-The hitscan enemies should have more noticeable aggro and attack sounds. You need to be able to localize them by sound alone so you can take cover.
-The silent ghosts in the crypts are just cheap. The other nearly-invisible ghosts were enough.
-Games shouldn't have dead ends with nothing in them.
-It's really easy to get lost (and not in a good way) with the lack of landmarks.
-Gave up on Garden Shuffle after failing to find the yellow key after combing through the level several times.
-It took me ages to find the skeleton closet in River Rumble. I was stuck at 97 enemies humping every wall in the level. Was starting to think it was a bug.
-There's no reason to ever use anything but the shotgun other than running out of ammo. Shooters should incentivize to to use different weapons in different situations organically. Look at Serious Sam for a perfect example.
-Map screen should show level names.
-The bush enemies are too quiet.
-Those robed enemies in the graveyard are way more engaging to fight than the rest.
-Those girl enemies in the swamp are bullshit. You need to give the player time to react to that kind of thing.
-Right Enter doesn't work.
Played up until Midnight Grove.
