Your game feal really juicy and playing it is quit fun. Sometimes it is a bit hard to get the desired input right, but with some practice it works well. The game made it into my favorites of the jam video.

Thanks for all your votes and comments! I just released a Redux version, featuring new boss attacks, improved balance and ui, mech upgrade pickups and lots of small improvements and tweaks.

Oh really cool entry!  I love the visual style, very unique and impressionistic.  The game play is also clever using just one button.  Great job 5 stars!  Please check out my entry if you have time, good day!

Cool game! I think it's more interesting to me, than fun to play, but still. I did not think someone would pull off "one sprite" in such a visually complex and cool way!

Initially I also considered making a 1-button combo game, but I'm glad I didn't since you set the bar so high! Really great execution, the deep mechanics feel great and the gameplay is framed around the core idea in a way that makes the whole experience feel very cohesive - wonderful work, really!

Post-jam Redux version is now officially in the works.

Really good game! the music is good. the graphics do sometimes hurt a bit to look at though when it gets chaotic.

the gameplay is very fun, although a bit to challenging for me (although i didn't play a lot of the game).

Oh hey, Bio made a quick showcase for the game. Thanks!

Hands down of the best game in the jam.

It felt really awesome to do all the combos, especially jet jump + super dash + barrier + rail gun.

Super satisfying and engaging to play! Good job!

Hey, we made a GMTK game too. Check it out!

Really cool idea and brilliant execution! a bit challenging as well!

Interesting, fits the theme like a glove and true to your other work; easy to learn yet hard to master.
Great job!

Just amazing, really hard but I want to put in effort to figure it out. The art style is impeccable, and the game design and controls really makes me feel like i'm operating the mech. It is also very clear that a lot of time and effort was put into making sure each button input combination was clear and intuitive. Great work.  

the game was semi hard to play but it just looks so cool and the concept is awesome. I really was impressed with all that was accomplished in a jam game. This was the first game I saw progress of that I immediately wanted to play and I was not dissapointed

That was very hard to master and it require me to keep calm unlike the usual button mashing style I use. The art style is also amazingly clever and totally fits the sci-fi theme of the game. Absolutely well done.

Very clever and original, well done :D. It's hard in the beginning but after 2/3 times you start to get the controllers, very nice. I liked! ps: One sprite, one input! you nailed it!

Somehow you managed to make a fighting game with only one button. I think the idea is very unique though it is very frustrating to play. I think it would have been better if the possible combinations were lower.  There also seems to be a problem with inputs not being registered properly sometimes. I think the game would've been better if there was less of a focus on platforming since that is the most frustrating part.

The art style is super unique but the noise makes it kind of hard to understand what's going on.

But for a 2 day jam entry, this is very good. 

Thanks for all your kind words. There are tons of little things I still want to fix and some stuff didn't make it into the game in time. I'll probably put together a post-jam redux version at some point. Potentially featuring mech upgrade, more boss attacks, better balance and larger level variety. Stay tuned!

This is a crazy game. The art and controls are so unique, and the railgun is very impressive to look at.

Well done !
