I enjoyed the first spikes puzzles but I found the first boss to be too challenging even after reading the hints. The spikes on the sides were a little bit unnecessary, taking into account we didn't even know what to do. So only thing left was doding both the projectiles and the boss itself, so 3 different challenges all while not knowing exactly what to do. It's just too much for a first level boss. Saddly, I wasn't able to go further. On the other hand, the art is very cute and the game has very engaging music!
