Thanks for the feedback, I agree that something should be done to make it simpler to click on the blocks, but I was not able to find and implament a good solution for that before the time ran out.

A possible solution I just thought of when you said that, would be a time freeze where when you held right-click the game would freeze until rightclick was released. I'll try adding that now and see if it works, although I won't be able to update the game-jam version so a seprate download would be nessassary.
