A lot of things here that feel like a gameboy game, like the slight delay on the swing on the bat of all things actually reminds me of a specific gameboy game (a Star Wars licensed game) that I have the actual gameboy cart of, the visual style evokes the feel of gameboy quite well for the most part, the song that plays feels mostly gameboy enough, though I do have one slight gripe on that front: The particle effects feel a bit more than what gameboy could've done. Still, very small gripe on that front, overall it's evoking that feel well.

Gameplay is quite good feeling here, I can't think of another game off the top of my head with a jump as low as you start with in this game where the jump still actually felt good to use. (Of course, this being a Metroidvania, it gets higher over time. Still feels good.)

Also, the ending got a good chuckle out of me.

Great entry you have here.

btw: Encountered a weird visual bug where if you press a button during the opening cutscene, the title screen text flashes again. Nothing huge, but worth a mention.

Cool! Nice graphics and music, no sfx though, that would have been a very nice addition. Unfortunately shift did not work for the browser, so I did not manage to finish it. I very much enjoyed the fast running and jumping pace though.

Despite the slow swing speed, I found the bat to be better than the gun.

Gameplay worked fairly well, though the repeatable control tutorials were too easy to accidentally retrigger. Found some animation glitches, such as going into a wall slide from standing on the elevator as it descended. But the game played fairly well in spite of these. Movement was on the fast side, but controllable. Upgrades gave a very Metroidvania progression pattern.

In short, a good little game.

Well done!

Cute little platformer. I like that you haunted game boys are a very nice idea :D

Really nice game. The art, music and gameplay are all great.

At least she got a new pair of shoes out of it

Hitting Game Boys with a bat is oddly satisfying, and the scatter effect adds a nice touch.

Nice game, simple but fun. The music is great as well. I really liked the idea to add backtracking mechanics to progress in the game.

I really like the pixelart and your idea. very cool
