Those holes are supposed to be lava on the floor if you are talking about those red tiles top down character can't pass. They were animated water-ish tiles which would have made it a lot more different but Unity decided that nah, animated tiles doesn't work in builds :( But yeah I probably could have made something else for that tile. There might be more levels coming if we feel like working more on it because we only made half of what we brainstormed haha. Thanks for liking our game!
