Review notes
Tidalis is worth a closer look if you want great with friends, emotional story, solo-friendly, and replayable.
Best for players who want emotional story, body horror, strong atmosphere, and great with friends.
Check more carefully if you dislike repetition or grind and unclear onboarding.
great-with-friends
FitIt tends to be better when shared with friends.
emotional-story
ToneThe story is framed as affecting rather than just plot-heavy.
solo-friendly
FitIt still makes sense as a solo play choice.
replayable
FitThe structure gives reasons to return rather than finish once.
grindy
FrictionThe loop may feel repetitive if you dislike grind.
body-horror
SettingGrotesque bodies, mutation, or physical corruption are part of the texture.
strong-atmosphere
ToneThe mood, place, and presentation carry a lot of the experience.
chaotic-fun
ToneThe appeal is messy, funny, and unpredictable rather than polished calm.

So, basically, you are not trying to build colour "areas" to eradicate the blocks, you are trying to build "pipelines" to ensure…Since it has local coop, with different players for keyboard and mouse.Finally, there is Adventure mode, which is the main single-player campaign.Seriously, those weird mutated animal things in the background are deeply disturbing.Why it fits
Check it if you want casual filtered by single-player, co-op.
