This was a fun game to play. Short and to the point. Controls are simple and not hard to pick on the ammo switch mechanic.
What I liked:
1. Fun gameplay
2. Visuals are very atmospheric and convey the sense of spookiness
3. Music and sound effects were good
4. Cool easter eggs hidden in the game (I found one)
5. The boss fight at the end, albeit a bit gimmecky, was a good addition
What I didn't like:
1. the player movement is momentum based, which is not a big deal, but I would prefer some snappier movement myself
2. One particular section felt a bit unfair. It's the one where you suddenly get surrounded from both sides by spooders with little time to react. I know there's a secret passage in that area (I discovered it by going the other way), but maybe adding some indication to that passage would make this section more fair to the player
All in all, I really enjoyed playing this game. Well done
