This was pretty awesome, deserved way more attention in the jam! Also I managed to defeat the boss. The sounds for collecting pickups I'm really not a fan of, I thought it was rather distracting. I think you mentioned in your video you are not too well versed in SFX design? I would reuse stock SFX and modify & combine them to fit your own needs rather then making from scratch if you did that. FX was pretty awesome, I think lacking screen-shake would be my only gripe, there is a mix of styles with it though it looks like the explosions are pixelated but the rest of the game isn't. I think the camera is zoomed in a little too much, I would have preferred if the entire game was either more overhead or zoomed out, though I get why you would want to show off that awesome mech model. The boss took sooo many hits even when upgraded, still felt satisfying to take them down! Would definitely want to see this as a full game.

I feel bad for the aliens, what did they do to deserve this? The mech feels really good to control. I wasn't getting a good idea of where to go / what to do except kill aliens.

Mech movement is fun, especially the dash. Had fun blasting!!

This game felt really polished despite the prototype graphics, and the juice on this game is really well done. Honestly the game is quite fun and enjoyable, even though it feels barebones. As the guy below me said, the camera for the boss was a bit wild, and without a health bar or some kind of indicator I was kind of left confused during the fight. Anyway, well done!

Nice game, had a blast blowing up buildings! The way they get destroyed feels nice - really feels like a building is collapsing.

Two health system is interesting, there is potential for tighter level design with it. 
Right click zoom feels weird, not sure it was necessary, maybe could zoom out instead? Would help with the boss fight - camera there kept turning in circles, it was a bit dizzying. 

Tutorial was nicely written, but could have been faster.
Difficulty was alright - took a bit to learn to be careful, then became much easier, at least until the boss fight, where it was challenging again.

Not seeing a health indicator for boss made me realize how important they are. We forgot to add it to our own game as well (all nighters before submission due time are rough)

Anyway, thank you for making this game, it was fun!

Great sound and visual effects. Also surprisingly good movement of the mech and camera. I could see this being developed further with more enemies, it reminds me a bit of Helldivers 1!
