Quality of game is high in terms of art and sound.
However, level design can be improved. While there are enemies, attacking them is pointless, making it feel like the attack button is just for show.
Furthermore, there is no ramp up in difficulty as the game progresses. When the final challenge was just to jump on top of a moving platform, I thought: "That's it?".
Also, I was teased that we will be able to jump to the other side of the hole at the start of the game, but left disappointed in never knowing what was on the other side.
Overall, the game has a good foundation, but doesn't have a very strong payoff... yet. Keep up the good work!
