Interesting. I have no idea why R to reset wouldn't work. also in-game I thought I said to use space to interact. yeah, I will fix collisions. That is something that seemed like a problem but for some reason, I didn't fix it.
Ah my mistake for phrasing that poorly. R to reset worked just fine. Even though I restarted every time I got to the sand part, the avatars collided with the walls and failed to move. As a result I couldn't progress past that level.
That makes more sense. I listed hints for all the levels, if you wish to finish the game, you can check those out. I told some others this, but I am planning once the rating is over to try and update this game to be a lot better.
