Would love to see more (hard) levels in the future, or maybe a sequel with more twists like rotating tiles etc.?

First of all, I'm really enjoying the game, I love minimalist puzzlers. However Im losing my ♥♥♥♥♥♥♥♥ mind over this level, It feels like I've cleared most of the tiles in what it seems the "intended" way but then I just cant finish the last section I know this means that I must have made a mistake somewhere but for the love of all that is golden I really cannot see where here's a screenshot of my so called progress ...

In later levels, say, 39+, if you play in fullscreen mode, you won't see some pieces - they are outside the view area, which covers only the middle square of the screen. Changing to maximized window shows all the play area, including invisible pieces. This bug is also present in at least one more game you made, though currently I can't remember which one - I have (and played) all of them :)...

I'm already on 49/50. I usually have more trouble with puzzles like these but I guess not this time. On level 49 (and this is not a breaker/stopper), one of the idle game pieces is partially off-screen. My window is 21 blocks/units wide, and the 8 "J" piece in the lower-right is just outside that. Not a show-stopper, just letting you know....
