The game is amazing to play, the movement feels awesome, and the visuals and sound design are gorgeous. But there are some design problems
First of all, the weapons. There are 2 flaws with the weapons. The first flaw is that they are not balanced. The OSU tablet is so confusing to use, and I gave up using it halfway through. The pickaxe is ok I guess, and the microphone shoots too slow and deals too little dps to be useful. The second flaw is that the only reason to ever use the weapon is the boss fight. The drones do little damage and the mosquitos can be easily avoided, so I just didn't care to use my weapons on them and just did the platforming
Secondly, the boss fight herself. This is probably a skill issue but with the weapons I have, it was very difficult. The only way I could beat Evil Neuro was by jumping on her head with the pickaxe and spam-clicking since Evil doesn't fly close enough to hit with the pickaxe. I also tried to beat her with the microphone but with the little dps it has, I just gave up on the 3rd attempt.
Overall, I enjoyed playing the game and had a ton of fun, but those 2 issues need ironing out
