Yes, level 2 is tricky but you are correct, from level 3 onwards that you get plenty of opportunities to get your revenge on them - and it's most satisfying!
Maybe you got a tough run on the RNG? I've had it happen before - some of the shapes are mean. So I'm considering fudging the RNG even more so the 'kinder' blocks spawn more often (actually I have 'staircase' and 'inverse staircase' shapes in my shapes.json to do that already). Those two fit together nicely.
Thanks for playing and hope you'll give it another shot as it opens up after the high explosives show up in level 3!
