A new computer later and I am now back up and running. This is a pretty sizable QoL update for this game that majorly overhauls a few of the biggest pain points:

The Greenhouse

• Replaced final challenge of the level with a new one after player feedback said original puzzle was inconsistent 
• Reconstructed several challenges to allow for more movement 
• Retextured lower half of level to differentiate from different sections of level
• Several bug fixes related to collision on lower levels 

Extraterrestrial Defense

• Changed the behavior of the cannons to be much friendly to the player 
• Altered the placement of several projectiles and speeds to make challenges more consistent 
• Rebuilt final area of level to give the player more space to move 

General

• Can now access final two levels from the main menu, no longer need to complete remainder of game to play 
  • Progress in these levels will carry over into the main game if the player continues, and the dialogue will try it's best to account for it 
• Gravity change checks should no longer "stack" 
• Made a number of checkpoints automatically mark when crossing their plane 
• Streamlined tutorial level to be quicker and more effective
