Thanks so much for taking the time to play and give such meaningful feedback. I really appreciate it.
I've never heard of Lemmings before, but after looking it up I'm honored that this could be compared and it does feel like a similar experience!
You have a lot of great points, I'd like to take the time (as you suggested) to design a proper introductory experience. I had actually hoped to build the level in a format that we would unlock some tools or characters as we dug deeper that allowed us to explore previous areas... but (as with most of my jams) I'm still learning to prioritize my time properly and not get carried away with features and tools.
Regardless thanks for everything and I'd love to do an updated version for the following jam
