The puzzle elements that the egg gun added to the levels was just the right amount of making you feel smart but never actually being annoying. That's a tough balance and I think this was done perfectly . I appreciate you having the level select open from the beginning and it encouraged me to pick and try different levels without it ever feeling like a chore having to replay earlier levels.
I had a good time and as someone who ALSO used GDevelop for the jam, it's always interesting to see what others put together with that engine! Overall, good stuff.
