Absolutely lovely game, especially for a jam! Very impressive, would absolutely be interested in seeing a game like this fleshed out. I am a big fan of Metal Gear, and the inspiration is very apparent so that is a big plus for me, then wrap it in a magical girl bow? Beautiful. Not to mention the pixel art was so on point and it would fit naturally alongside many other Gameboy Color style games.
Critiques and bugs:
*The phase button was mapped to my V key instead of C, also I never really found it to be useful as often when there were projectiles or enemies coming towards me it would be better to use my gloves anyways. And while there were certain sections, like the final boss, where it would be useful to avoid getting hit, the fact that it draws from the same energy as your weapon means you are just stuck there waiting and hoping the timing works out that when you unphase you don't get hit.
*After doing a double jump the dodge roll wouldn't work.
*Because you can't aim up or down with your gloves sometimes you could get hit while in a corner or on a small platform which didn't feel very fair.
*Logs in the conveyor belt section would follow my movement direction.
*Fire only shot out sideways, even if it as on the ceiling.
*The final boss needs some work. It took a while to figure out due to the fact that we had never needed to destroy the turrets that shot at us when we were spotted, and so it wasn't intuitive to think that was what was needed. Doubly so due to the fact that your eyes are naturally drawn to the gauntlets in the foreground, first thought was that I needed to either hit those or the gears behind them after I baited them to drop down. Either that or hit the eye. Additionally, because of the aforementioned lack of directional attacks, sometimes a bullet would be coming towards you while you were hiding from the eye, and it was JUST barely too high to stop with your glove, but not high enough to end up hitting you and thus knocking you into the sightline of the boss which felt pretty crappy.
Overall though, the experience was fun, short, sweet, and in a very neat package. With some more love and care this could easily be a big hit.
