I'm not very good at it but I like the variety of upgrades and the otter boss is cute! I like the number of bosses I saw too. I think a bit more range on your attacks and more aggressive enemies that try to close the gap on you would make the game "easier" but feel balanced in the extra ability to do damage. I felt, as it currently is, in order to get close enough to do damage I was putting myself too much at risk of them doing their own ranged attacks (the tornado/explosion damage) which had more range and did more damage to my 2-3 hearts vs the bosses' larger HP bar.

Drentsoft Games Ltd, thank you! Yes, the range of the default attack needs to be a little bigger at the start, as well the number of starting hearts for the player. Otherwise, although still doable, most people found it "extra" challenging.
Learn to properly adjust and calibrate difficulty is my next goal. It's fun!
