Hi, i've played and rated your game. It's a good start. Next time you should use a background layer and not the default unity skybox. Also a tip for endless runner, make them endless with a highscore system and you  not have to let the player win. Let them just know their highscore and get them back on track. But nevertheless, well done!

Interesting idea for a game. Great job 

I like the concept =)

but the game does not look appealing and a bit buggy but still nice GAME !!!

Addictive like the google t-rex game. You could have changed some few stuff like adding emissive materials to the sprites. Music would make the game interesting and exciting. Other than that well done you two.

Fun game :) I really like endless runners, so I've enjoyed the idea.

It's a great submission for the first gamejam and also it might be easily upgraded to look and feel really well :)

Some suggestions:

< In LightingSettings you can change skybox to none and on MainCamera set SolidColor and make it black, it would make game look much more  better with black background :)

< I like the idea of using rewind as save point. Hope there would be a bit of difference on taking a blue square, for example changing mechanic to flying instead of walking, but it's nice that it changes shape anyway ;)

< Some music and sounds are always good to make your game feel better, even if they are just taken from some free site.

< If you work with primary shapes it's good to put some emissive material on them, it would look really cool.

Anyway, a great game! Hope you upgrade it in a future.
