Really nice simple game. Can actually see it playing on a gameboy. Sometimes the bullets of the enemies are difficult to distinguish because of the background animation, but when you get hit for the first time you start to recognize them. I liked it.

The window size option is a thing that is necessary in almost every single game in this jam, so kudos for adding such a nice feature! Although, the maximum re-scaling still isn't enough (at least for my screen, I don't know if screen size affects it).

It's a simple concept, similar to the classic Shoot Em' Ups, but it's fun and it works the way it's intended to :) It also feels like a Gameboy game due to the way it looks, plays and sounds.

Great job! :)

A very funny game! It would be great if your game had sub bosses :)

(I loved the background sound)

I love the color palettes, and I really like the sprites! They feel like a really neat in-between of galaxian and space invaders.

In terms of gameplay, I think the way you made the enemies shoot is very cool. Picking a random enemy to shoot every second or so is a neat way of increasing the difficulty as you clear a stage, as the last enemy you take out will be firing constantly.

In terms of criticism, I think the lowest row of enemies is a bit too low on the screen. Shots fired from that row go from being fired to killing the player in a matter of only a few frames, and it feels a bit cheap some times.

Additionally, I think it's missing a certain energy in the moment-to-moment gameplay. This is partially due to the fact that none of the enemy attacks are targeted towards the player. As such, the only time I'm in danger is when I put myself in danger, which means most players are going to go about clearing the level in a slow, methodical way. I think it would feel a lot more tense and satisfying if there were another constant threat to keep the player on their toes. This could even just be a time limit, so the player has to focus on clearing the enemies quickly in each level. It's a rule of thumb in game design that players will tend to interact with your game in the least interesting way possible (because that's usually the safest route to victory) so it's important to notice when that happens and force them to engage with the systems head on.

All in all, great job on your game! It's already pretty solid, and with a couple tweaks I think it'll be elevated to the next level.

Great space invaders clone and really challenging!

Awesome game, reminds me of my submission last year. great work!

Good job! Being able to set your own scale is a really nice thing for the player, I'll definitely do something like that in the future!

Good times of Galaga!

I remembered Sunday afternoons killing galactic insects!

A very well made copy! Congratulations!

There's a pretty vintage feeling to pretty much every aspect of this game that I can appreciate, it's certainly fun and I don't really see anything here that a real Game Boy couldn't really do, though the sound could have been a little more accurate... Good job anyway!

Fun game! It was hard to follow the enemies pattern, but managed  to reach stage 8. I'll try again later! Much gameboyish as well.

It's actually kinda charming in its simplicity ~ I feel there should be a short pause when the player dies before the next ship respawns, but other than that it's quite well put together and it plays rock solidly !

This game looks like something that would be released in the early years of the gameboy, due to it simpleness, I liked it.

Damn got myself to Phase05 i think ? Scr:0890. Addicting! Altough i would actually prefer some music, why not some calm music in the background for contrast :D  I could easily create one for you if to continue with this simple shooter.

Simple and fun! It looks like it would actually run on a gameboy!

The controls were kinda stiff in my opinion. The players shots take a few milliseconds to fire after you press the button, and It makes it feel more like a real gameboy, but worse for overall gameplay.

The art style is simple and cute :)

But in my opinion the game mechanics are a bit too simplistic

Loved the simplistic design, even if i dont think it's gameboyish, it's more of a late 80's game,  it resembles more to an old atari game with palette swapping. Also, keepin it classic as far as gameplay is concerned works great, especially with that minimalist sprite work of yours, in general, it's a fun, classical game, gud job ! Rated it ;)

Simple game with really good level design.

My high score, but I still want to unlock the special movement.

Simple but quite fun and love the different palettes. Great work!
