Thanks for playing, and yes, this game has been built for real hardware, I used an omega DE to test it as well.
What kind of issue are you running into on hardware?
Unfortunately no, only .GBA rom files are accepted in this jam.
There is an exception where you can upload a game that was made in GB studio so long as it has been exported as a .gba file which can only be done with an external tool on a specific version. (see "Can I use GB Studio?" in the jam overview F.A.Qs)
I think this is a great idea for building on the core of tetris, it has a nice style and a fun concept.
I'm sure you've heard this a lot already but yeah, A+B should be for rotation, kind of leaves the right hand with nothing to do without that.
Here's an unsolicited level idea too, once a line is cleared, clear the line blocks but "forget" to move the pieces above the cleared line down.
Thanks again, the turret desync issue has been fixed.
The timings for the 3rd bullet run segment are tight but weren't changed, instead another issue of knockback occurring during the invulnerability you get after being hit was fixed, this solves the issues on the 3rd bullet run.
Thanks for comments and I hope you enjoy.
