Thanks a lot for the feedback and playing my game! I too felt it was little to linear, its something I need to fix in future entries. The barn background was the first thing cut when I started running out of time. I thought it would be better for the player to recognize more important things, but we all make assumptions that don't turn out to be true.
The divebomb issue I saw at the end of testing. What I would have done was create a separate hurtbox for the dive and sized it fairly. I just didn't have time at that point. And yeah, I love my maps! The more rooms you have, the more important it is to have one. And being dynamic really helps.
Thanks for playing!
Edit: My feedback will be delayed. I'm recording my playthroughs and ratings and uploading them.
