I'm really enjoying making these! Takes some time to make sure it can be done - making puzzles difficult is difficult!
I tried to make this one different by making it punish you if you do things in an incorrect order. As you can see, there is a massive gap in the bottom left that I will fill eventually, just want to get feedback on how it is so far, and if it is a good style of game.
Edit: Including my even more up to date version. I have slightly changed a few things to make previously useless blocks more necessary. If any of you try this let me know what you think!
