I'm not sure if it's just me, but the first boss fight has 3 bugs that I noticed
1: The tentacle things sometimes do not grab the player
2: The boss shows the wrong color for the safe platform
3:after getting grabbed and escaping the boss, sometimes the boss does not go away and just stands there softlocking the game
All these bugs are seemingly random. I have yet to play through the boss where one of these bugs has not occurred
