I liked the idea! but its a bit difficult for me! (enemies are very fast approaching)

Graphics are nice! I'd like to hear a soundtrack in the background and some visual feedback on collisions would improve it much!

Good job!

I found it tough to control vertical movement and music would've been nice.  It is  fun and I liked the parallax effect.  Cool to let the user change the pallet too. Nice entry!

Cool mechanic and the way the ship controls gives it a nice touch of difficulty!

Water cooling your weapons is a great mechanic!

If there was a water enemy lurking, limiting the time you spend there, it'd add a bit of pressure instead of being too much of a safe space. Cool game!

its fun :D
the idea to splash in the water is really nice and I like it.
game definetly feels gameboy-y in all aspects.
dont see how it relates to space though. I assume because its a space ship that fights aliens? having a different setting would enforce that (like death star in the background instead of sea and clouds).
execution is well done though.
what tools did you use in making this game?

This game is definitely very, very promising!

The art is definitely good, and the overheating mechanic is certainly a smart and unique one!

I even like the ability to swap palletes on the fly. I like that kind of stuff! (I even put it in my own game lol)

Only thing lacking is the sound department. There's definitely good SFX, it's merely just now the fact that the "music" is literally the pulse (and noise, I think) channels playing like one note and then looping till the end of time 

I love the idea of using the water to manage your heat build up.

i feel like the jet moves a bit too fast, maybe you could of had the B button to  shift you to a precision mode, so you can slow down to aim,  but speed up to dodge more easily.

still it was fun to play.

What a great idea that you have to cool the ship in the water.

Nice shooter. Overheating is a cool idea (although the sound when in water is annoying as it keeps repeating) and it tends to crash every time I restart but it's a fun game and looks really good!

I liked everything (👍 ͡ᵔ ͜ʖ ͡ᵔ)👍

This is one of the prettiest GB / GBC ROM games I've seen so far! The horizontal parallax effect is so cool!

Fantastic! Great work!

Really clever overheating mechanic. Kinda reminded me of Downwell's gunboots in terms of simplicity/originality. Also cool that it's a real gb game! A little explosion whenever you kill an enemy would be a nice addition.

Fun little shoot em up, I liked how you can change the color palette.  The overheating mechanic was a cool gameplay additions. The highest score I got was 37.

Cool shooter, I liked the graphics and sound effects. So cool you got it working on GBC! Without needing to go to the water, I found that there wasn't much reason to move. Maybe dodging could be encouraged if the score was also based on time. The changing colour palettes were a nice touch :) 

Cute little shooter. Love the color palettes, the enemy designs, the parallax backgrounds. Very atmospheric overall. Sound effects are good, too. And there are some very original touches--the angled shots, the heat/cooling mechanic.

I found that the character moved too fast for me to control comfortably. And I generally didn't have time to destroy many enemies, since they require multiple hits; rather, I found myself dodging them if I wanted to survive. I think the speed of the player character may need some balancing, especially since you progress horizontally (i.e., you are strafing along the vertical, narrower axis).

Cool game! The parallax effect here is great. The heat mechanic was a cool idea and color palette changer was a nice touch. 

Great game! The graphics & gameplay are well done. The overheating mechanic is an interesting addition.

Loved your game! Im impressed that you were able to add so many sprites and make the gameplay so smooth playable at the original hardware! It has the diferencial that you need to dive in water to cool down, great idea! I think you could add  a high score sysntem and I can imagine a story mode with huge bosses! 

Really good game! I like the idea of diving in the water to cool down but I’m unsure how the game fits the Space theme.

Its a little glitchy but still playable.

Maybe have a soft musical song in the background to help it continue the excitement for the player. 

Its hard to stay away from the water.

I think if you make the overheating system slower or while not firing it slowly depletes it self.  To give the player more freedom to use the fun ship controls you have made. 

Visuals and all the other sound effects are spot on.  Looks amazing,  fun ship controls.

Overall nice job!
