A minor update:

• Fixed crash bug upon restarting. Incredibly hard to reproduce, so not guaranteed, so if you you get a crash on restarting a level, or starting a new level let me know.  This is incredibly rare, but I have noticed it to happen only on Windows builds, not Linux.
• Collision fixes on some curved walls and on crates.
• Geometry fix on level 5
• Removed/changed enemy spawns on level 2 when picking up red key.  Before fixing sight/collision issues with the rails, enemies could not see the player down below.  Upon fixing this, all enemies will be triggered and it's impossible to really beat the enemies.  They have been removed or ensured they can't see the player.
• Nerfed the tentacles.  They are now staggered with 2 hits. Should make them seem less spongey and more manageable.
• Exported with Godot 3.4.2.
