Nice art and music. The background was glitching out which was a bit distracting. I like the idea, it is very ambitious. I just didn't find a use for combining different elements together. The 3 enemy types had weaknesses : 1. water-water, 2. fire-fire, 3. rock-rock . Not using other combinations was a bit of a waste. Also, it would've been nice to see the elements impacting the behaviour of the gun in meaningful ways, for example fire-fire shoots fireballs, fire-water shoots a cloud of hot steam etc. The maps were a bit too big, in my opinion. I spent the majority of the gameplay trying to find that last remaining enemy. The enemies themselves didn't pose much of a threat and were easily defeated, which isn't very exciting. I think smaller maps with more and tougher enemies would've made for a more fun experience. Despite some problems, this idea is pretty great. The game that you've made is good, but has the potential to be even better.

The jetpack thing is really cool!!!!

Also would be cool if you checked my game :  https://itch.io/jam/brackeys-5/rate/927654

It's about a virus living inside a human's body!!!!

Really awesome idea! The mechanic of combining elements in your gun was really cool, and I liked how different enemies had different elements they were weak to. I also liked how the water gun was used to boost the player up, that was a cool movement mechanic. Some element combinations were missing and I found it odd how pressing the water element instantly filled it up, but I understand if that's just due to jam limitations, as this game seems pretty complex to code. The game really needs to let the player learn the game mechanics before it throws them in front of an enemy, since the mechanics are pretty complex. I lost 3/4 of my health to that first enemy just because I didn't know how to shoot or mix elements and the game didn't give me time to learn. Also I got softlocked in a pit:

But overall it is a really cool idea, if you add more unique interaction to mixing elements this definitely has potential to being more than a game jam game!

Even though my brain was hurting at the beginning trying to figure out what to press to shoot etc but once I got the hang of it it was a fun game! Find my video review below, oh and I did not fully figure out the combined elements as on what was good or bad haha

The game is quite hard and repetitive but I like the way you use wind bullet as jetpack :)

Cool game, it was very interesting to see something like 2D magika with a rocket jump.

Very good game i love the blending element system i think it fits well in the theme good job.

also if you have time could you check my game feedbacks are welcome :)

Liked the idea ! I'd love to have more real combinations right at the beginning. 

Unfortunately I got one bug, I hit the ground too hard and got stuck into it. Not a big deal tho. I'd suggest you to put a cool down on the air combination, it's quite easy to use it as you want, and do it repeatedly to fly. 

Great work on the art, as well ! 

It took me awhile to get used to it (while being shot at haha). But once I did I had a lot of fun zooming around the levels! Didn't expect that. 

I found the enemies had 1 elemental weakness and just used those. I was hoping for more tutorial about combining elements, but didn't need them which is kind of a weakness to the theme. But I definitely had fun!
