Let's trade feedback! I submitted a project too.

• Gameplay: Co-Op endless runner, good direction to take this. I can see kids trying this on iPads as well as a potential mobile version using two side of the phone to compete. I could pass the time so easily on this when playing with my siblings. It's also funny art style too and low pressure overall.
• Art: Good use of the minimalist 3D Models, level blocks and traps. It's so simple, why hasn't anyone thought of this design yet in co-op format. I like you have the hazards going toward the center of the screen instead of the other way around. Player hero always stays centered, another reason there's potential for Mobile port.

Future Enhancements:

1. Character Picker for each side----just visual skin changes, doesn't have to be stat or tangible differences. Because the chibi sci-fi art style just works.
2. Difficulty picker----for us hyper-competitive folks. 
3. UI Hits Counter ---- add a number next to the lightning health bar that shows how many more hits we can take. (When the lightning is full, it has a 5. When the lighting is almost empty, it has 1 next to it. For better clarity). 
4. Hazard animations----can potentially add unique animations to the hazards to make it feel more lively than static hazards. Boost platforms---like in Crash Bandicoot that help us run faster or jet over an obstacle. 
5. Collectibles----maybe simple hero collectibles on the paths. Like a floating hat that you have to jump to collect and at the end of the round you can add it onto your character. So both players have alternative incentives to keep playing.

Wow really great take on a coop endless runner, I'm going to try it with my son later, I felt like I was fighting my brain to get some of the movies going at the same time :D Very cool! Great job! 

I really liked it! Amazing concept and use of the mouse! Really hard at first, but quickly becomes very satisfying. 

super awesome project! maybe a little on the harder side, but still fun

You really took those challenges personally :) Well done! Interesting idea and polished implementation. It was fun to play it 

You took on almost every challenge in this jam, great work!
