Really cool entry team, there's a lot of awesome stuff going on here, nice work everybody!! Right away the visuals are striking and are a great first impression for the player. The dark background has a great contrast with the brighter player and boss models that rally makes them pop. The boss animations and tentacle movements look amazing and feel very realistic (or at least as realistic as a giant purple tentacle monster can be lol). The destruction to the terrain when the boss spawns in is a cool touch. I really like the player mushroom model too, his mushroom cap reminds me of one of those samurai hats and I can totally see him being the hero of some universe.
The boss attacks are pretty fun and varied. They feel well-choreographed and well-telegraphed, and for the most part getting hit felt like my fault. Some knockback and particles when getting hit by the tentacle would be nice additions of juice too. The fight as a whole feels a bit too difficult but I think the boss is fine as is, imo the fix would be to increase the player speed just a bit. There were a bunch of times were it felt like I reacted to the boss attack quickly enough but then would just barely get clipped in an unsatisfying way. I think a touch more speed would fix this issue completely, while still preserving the boss rush challenge and the fun of grinding it out until you win. This would also make the kiting melee style combat even more fun imo. Another improvement would be some kind of boss health bar or other indicator. I wasn't able to beat the boss, but knowing how close I was getting to victory would have motivated me to keep trying. edit: I also think the theme application was fairly weak, the one room thing doesn't really effect the gameplay much and is kind of just the way any traditional boss fight is already setup.
The music and sfx are decent enough, but don't feel particularly inspired or unique to the world we are in. Not a huge deal but an area for improvement. Another small nitpick is that the blue orbs/bullets that the boss shoots don't feel like they match the general aesthetic of the rest of the game. That being said, I really enjoyed my time with your game and think you have a lot of potential here. The art is stunning and an easy 5/5 overall. The player model, boss, and environment are a very intriguing combination and make me interested in learning more about the lore of the game. The tentacle animations look great. The combat and attack patterns are fun and challenging and with a little bit of tweaking could be even better. You should all be proud of this entry, and I think you have a solid foundation with some good potential if you chose to keep exploring this game. Great job and keep up the good work!!
