A new early access build is now available for testing with a lot of little improvements and fixes based on playtesting and feedback:

Changes:

• New mechanic for placing blocks on later levels to mix up gameplay.
• Added a hover animation to some special blocks to indicate they can be clicked.
• Made background a little lighter and smoother.
• Vlobs spawning is now more generous with ones and twos for the last tiles before game over.
• Performance improvements.
• There's now a secret fps counter you can toggle on by clicking in the top right corner.
• Added Godot license text to credits menu.

Bug fixes:

• Fixed a lighting bug with special blocks and vlob popping slights.
• Fixed bug where the UI would block placing blobs bottom right corner on some window sizes.
• Fixed bug where you could get stuck in connection select mode by selecting a connection during the transition animation.

I look forward to hearing what you think of the game if you try it out!
