Hey! Thanks for playing the game and for the comment. Yes the game has a long way to go and what you mentioned are really some cool features yet to be implemented. I'm really motivated with your comments - that's why I posted a prototype build. For the next update, there will be some upgrade cards (like a roguelike game). Exploding crates/ barrel would be so much fun. I should look into that as well.
Destroyable environments are pretty fun - but ×10 times more work. But we'll see. Hopefully in the future :)
