All of the game was pretty good, but the boss fight was so random. When i died in the boss fight, it was due to bad spawns of the 'nut shaped' enemies. Those things spawn so much and are so fast that you're basically forced to take damage. The rest of the game felt too easy because of how much health the character had.
Other than those downsides, it is worth the time to play, especially compared to other games you have made.
