This is a pretty fun game! I can't quite pin down what I like so much, but it just
feels right and fun.
The tutorial was helpful, and I can't really think of any ways you could improve it. I had to reread the first one a couple times, but that was probably my fault.
As far as restarts go, the first couple tutorial levels went by smoothly. I had some trouble getting through the steel part of "Special Boxes", and ended up restarting four times before finally finding the right solution. This wasn't a bad thing though, since I was not annoyed at the game and more than anything eager to try again. The nuclear block part took me a couple tries, but I picked up the trick pretty easily.
I spent a minute studying "You're On Your Own", but ended up just clicking on blocks and somehow won with my first try.
"Crossword" took about 3-4 tries. I kept getting stuck with the round one at the bottom left.
"Watch Your Step!" was slightly more difficult, requiring 5 restarts before I finally found the solution. This was the first level where I felt noticeably proud that I beat it
On my fourth try, I beat the puzzle on the green board in "One For Each". It took one restart to beat the red puzzle. It took me 6 restarts to beat the yellow one, which only happened because I "accidentally" found the correct solution by clicking on a whim. I beat the blue one on my third try after a little experimenting and logic. All in all, it took me 12 restarts to beat "One For Each". This was noticeably more difficult than the previous level. Maybe there should be easier levels between this and "Watch Your Step!" to gradually bring you to this point. Perhaps one where you only have to deal with two "pads" of blocks.
I beat "Five Square" on my third try. I experimented with a couple blocks to see what the outcome would be, I then used a trick to successfully solve the puzzle.
Hover here for the trick.It took 7 restarts, but I finally beat "Now Try This!". This was a fun level which required me to think about the puzzle in different ways. An introduction to this type of puzzle would be nice in the tutorial, but not required.
When I submitted my name to the highscore, it beeped and the submit button can't be pressed anymore. However, I don't seem to be in the highscore list to the right... I am assuming that you update that list manually, or the game glitched.
