Hi. Thanks for your response :-).
Yes - the game is very hard. But if you haven't killed any bomb then I guess you might haven't charged your attack enough. Without charging an attack makes one damage and is very slow. You can charge this up to 20 damage and very fast. The bombs on start have 10LP.
So may give it a retry with longer charging - then you also have more time for aiming. I hope that helps :-)
Ofc I play your game as well - comment will follow :-)
