DAY 23
Got some REAL LIVE pixel art for the railgun here look:
The green panel is meant to display the current charge of the railgun.
I think it looks pretty alright. I wanted to make something bright and recognizable that makes you go "dang I wanna shoot that thing." Might do another pass on it later, but I'm also thinking I can get some mileage out of Unreal's regular UI tools to, say, shake the railgun around as it's charging or something along those lines.
I also worked a bit more on the enemies. Now they'll kill the player the moment one of them makes contact. I also started implementing a "stun" mechanic where any enemies you shoot get stunned for a little bit; I think this will add depth to the decision of which enemy you decide to shoot and when: should you quickly tap LMB to stun a few enemies for a little bit so you can charge up and kill another approaching enemy, or just focus on dealing as much damage as possible and lining up your shots to hit multiple enemies at once? I think after I implement this stun mechanic, and a spawner that spawns enemies every so often, the game will technically be fully playable, so I'm looking forward to testing all that out.
