Hi, congrats on your game! :) I think it would be interesting to consider the idea of not having an instakill when falling on wooden crates... From my point of view, it makes sense, but if it's too complicated to add, don't worry about it. :P
If you have some spare time, please try out my game. It's a classic space shooter from the 80s but with a personal touch. Please leave your honest feedback. :)
