I really like the style of the graphics and music in this game, but I did find the boss quite hard compared to the platforming section. It took me a while to work out how to beat the 2nd phase, but when I realised there's a 3rd phase even the 2nd one seemed not too difficult. I basically ended up hopping from the middle platform to the one to the left to get a few quick shots in before the boss fully raised its hand to attack. Not sure if this was the intended strategy but it worked in the end XP
