I'm very excited about this alpha! It has some great weapons/grapple improvements, neat story bits, a new food chain level featuring MEGABUNNY, and a wild new boss fight in zone 5.

Here's the official change list:

Additions/Changes:

• Improved 1-intro. The player actually rides the pod down in the beginning, a dude waves at you, and enemy spawn locations are marginally improved.
• Adding a foodchain mode for 5-1. Features the new megabunny and the ability to heal the collector!
• Adding 5-boss.
• BIG improvements to responsiveness and speed of fire for rapid-click firing of homing/charge guns. One normal shot fires immediately on mouse down now.
• Grappling hook now allows the player to hang onto terrain. The player can launch themselves from this position by moving said terrain.
• Grappling hook grapple and slam states should now be far clearer.
• Damage flash color is now orange, to help with player confusion when shooting enemies' glowing red bits. This may need balancing on orange-skied levels.
  

• Fixed missing arrow in 3-3 that confused some solving the tree puzzle.
• Player can no longer EMP while playing as the second character.
• Player grappling hook is now canceled/interrupted if the player is launched by terrain.
