I like the concept very much, however, I have a few issues with the game. The second level is very well designed, no problems there. The tutorial/antepiece is too much, Typically, the antepiece should be a zero-risk environment to test out your tools and experiment with ways to use your tools, however, I thought that having both a murder laser and a murder ball was a little too much. Already dying from hitting the “wrong” edges of the goal is a good tutorial, and I’m embarrassed to admit that I have accidentally triggered the door open and then closed it, running into the shut goal way more often than I should have.
I really liked the text-free tutorial, and you guys did well designing your minimal messaging around your appropriately minimal game (or vice-versa, whatever came first).
Would not be surprised to see this as a final project. A small game can give a small team a lot of room to work with regarding game feel and pure level design.
