I think this might be the hidden gem in this jam. The mechanics is super interesting and creative, and extremely on theme. Even in the earlier levels, I was already very impressed with the well-designed puzzles and implementation. but I keep getting surprised by addition of new content. The different mechanics are all cohesive and on-theme too. I like the minimal aesthetic and color scheme. The puzzles' difficulty curve was planned well. Got challenging towards the end, but never unfair.
By the nature of the game design, it takes some degree of perseverance to complete the end-game puzzles. Making a mistake in calculation requires a full reset. I can't think of an easy way to circumvent this, but I think players who are motivated enough or enjoy the challenge will have no issue pulling through.
Some UI elements can be improved. I was thrown off a bit trying to resize the early stages mask due to the presence of the Black dots are the cardinal points. The later addition of a resize option made this confusing. Might be better to leave out the black ones that are static, and make the resize points more obvious. The difference between the resize and move NPCs, as well as the manually activated vs the masked-over switches can also be made more distinct. The game would definitely benefit from enabling the "full-screen" button option on Itch to improve accessibility for people with poor eyesight. I'm not colorblind, but the choice of red/green might cause problems for those impaired, so many an option to switch to high contrast hues might help.
The let down here would be Audio. The SFX were jarring and can wear on the player as time goes by. The absence of a vol slider forced me to mute the game altogether eventually. A more pleasant choice of SFX and addition of some complementary BGM would go miles in improving game-feel.
That said, this is likely my favourite entry so far. I sunk more time into this than I should. But I always find myself intrigued by the ingenuity of game design in entries like this. Tremendous effort.
