I'm glad you liked the game ! Indeed this plugin is very cool, with it you can go 3d while keeping a top down view or go first person like I've done here.
Yes I thought it would be cool to limit the number of saves, it's an interesting challenge and since the game is not very long it's not too oppressive imo. I'm happy you enjoyed the spikes and hostile plants too, I wanted to give each area a very distinctive identity.
Thanks for this nice feedback !
