Pretty good game, especially considering the time crunch the developers were in when making it. If you guys plan on taking the game further, here are some comments and criticisms I had when playing.
Pros: I really liked both the music and art direction/animation, they don't become tiresome during repeat playthroughs, which is an issue a lot of games in this style fall into. The gameplay is fun but also simple, it doesn't take long to figure out the main mechanics of the game and effectively use them when playing.
Cons: The only major con for me would definitely be the fact that attacking in a vertical direction doesn't seem reliable. Both the grappling hook and the slash attack seem to only work in the horizontal direction, which makes it really annoying when an enemy is above or below you, especially when you are going up and down a vertical path. Maybe I'm missing something here but I don't think so. Other than that, there are just minor issues I have, like the short length of the game (which makes sense given the timeframe you were given to make it) and the difficulty being relatively low (this feels like the first level in a potentially longer game as it only took me 2 tries to get to the end, but this would make sense if your mindset in making this was as the beginning of a game you might make more of in the future, so it's not that big a deal), and the slippery movement (which I personally am not a fan of, however it's not a big deal when you get used to it).
I also ran into a few bugs where I would grapple and land out of bounds, but thats just a kink that would need to be ironed out if you continued developing this game, so it's fine. Overall, solid game with a good direction, and I would definitely play more if you decided to keep developing it.
