I like 1st level tutorial. Unfortunately the 2nd level was super confusing for me. The "Red Cell" was red square for me. You should be more explicit about what you mean, e.g. "red bar on the bottom of the screen" or maybe draw an arrow pointing the bar. Another confusing thing was that sometimes if I click on the bar nothing happened, sometimes the time was rewound. I had to go back to level 3 to understand it. It's explained, but the level doesn't require understanding it to pass. I'm still not getting the game as I can't pass the 5 level, because the time I can reverse the belt movement the block is already on the floor. Maybe I'm just too dumb to play it. The game looks really interesting and unique, but I'm just unable to grok it.
Thanks for the feedback, and no you're not the only one having issues with understanding the game mechanics :)
The UI was definitely a weak point of the game and everyone is having some difficulty getting a handle on how things work.
That "Red Cell" issue in particular is definitely confusing to most people.
Things for me a learn and use for my next game.
Thanks again and good luck with the Jam!
