Thank you so much for playing! I'm happy you noticed the variations in the bombs and explosion sounds! Personally I'm just bad at art, so I tried making up for it by adding these small polish details and I'm happy someone noticed. And don't worry about being bad, there's been quite a few people saying they got stuck at some point too so maybe I'm the one who's bad at level design, hahaha! I really wanted the game to not be too hard but I also don't wanted to give away the answer to the puzzles instantly, so I had to just ease them in with good level design which is pretty difficult.
But hey, if you wanna know the answer to that pole on the 3rd level, try not landing straight into it, instead of getting height to land on it, get height to put a landmine on top of it.
