Liked the game but it was a little up and down, controls were great, attack animations were lacking, some artwork was amazing, some was not, gameplay itself was brilliant, but lacked sound. There is the basis of a very fun game here, I think if this was a two week jam then we would have a solid entry. very good work for a second game though. 

I liked the design of the character and the bosses!

The gameplay needed some feedback on player actions via sound effects and some visual effects. I found the game pretty challenging and it would be nice if the bosses had a bit of a warning before they did their attacks.

Overall though, good job!

Very original!

The game is smooth, I like the art, but where is the music, adding them will make the game a lot better,  good game over all, hope you try mine as well.

The game is fun and the boss designs are solid. Only negative note I have is that it could use some audio. 

Really cool boss fights. With diverse and interesting patterns.

It lacks a bit of feedback on the actions(and the audio) but it could be a great idea this top down boss rush!

Nice job! I liked the unique designs, patterns, and the variety of weapons.

As others have said, audio, weapon icons, etc. would be nice in the future. The hitboxes for the character could be a bit more forgiving in my opinion as some things seemed to hit me that felt like they shouldn't have, but that's a tuning/opinion thing.

I particularly the different enemies and designs--good job!

A solid foundation for a good game. Some visual feedback on what weapons are equipped, when you hit an enemy and a few other things would definitely enhance the gameplay. The game has no sound, but overall that does not detract from the gameplay. If this game was to be developed further, I'm sure I would enjoy it immensely.

Nice start of gameplay but keep working :) Add VFX, Audio, UI and it will be better.

It's all there, but a few additions (visual feedback, UI and some gameplay tweaks) would greatly enhance your game!

An interesting and unique concept, with a few small problems.

The art is very nice, and and it was fun to try out the weapons and work out how the different bosses acted. There is nothing in the UI to indicate which weapon is equipped so it was hard to keep track, and as others have said the lack of visual and audio feedback upon dealing and taking damage meant I was unsure of whether some of my attacks were hitting, and I died unexpectedly a couple of times. However, I did beat the game, and then replayed a couple times to test the weapons, which are all very unique, and I understand the absence of some features as I had to cut a few things in my game as well due to the Jam time limit.

Overall, with the addition of some more UI and damage feedback, this could be an even better game.

I really liked that the bosses were so different, it added a lot of variety! I am really not good at the game :D, but I had fun playing it! Well-made :)

This was a fun entry I liked how each boss had a unique design and pattern. Also like how each of the weapons have different playstyle. With a bit more polish this would be even better.

I had some issues controlling the weapon with my Magic Mouse, but otherwise fun to play.  Great entry!

I love the boss designs. Each is unique in looks and attacks which is super cool. The game is certainly challenging but also quite fun. My only feedback is that sound and visual feedback for damage and attacks would go a long way. I understand its a game jam though so time constraints mess with everything. Still a super awesome game. Very well done :)

Really nice designs and variety for each of the boss enemies.

Would have been nice to have a bit more visual / audio feedback for when the player takes a hit.

Overall a nice level of challenge too.

I love that each of the bosses has a different moveset, and a unique design. The weapon variety is really great too. I think the core mechanics are great and all that's left is just to add that extra oomph.  Also the writing was neat!

This is pretty good for your second game! I think boss rush games are pretty cool and I like your execution. Each boss felt unique and I liked having different options for attacking, each weapon also being pretty unique. I've noticed there's a boss rush jam coming up if you're looking for more jams to join ^̮^. One thing I'll suggest though is adding more game feel and feedback. As InvalidSpacebar said it could really use some audio. SFX will help sell impacts and make players more aware of when they take or deal damage. Things like particle effects, screen shake, hitstop,  etc. will also really help here.

It could definitely use some music/sound effects, it's got a nice and quick flash game feel to it though and isn't a bad start to something!
