A fun idea, though the controls aren’t very precise. It seems you can only turn in 60-degree increments, which makes it very difficult to avoid enemies. I would also recommend changing the collision detection a little on explosions, because barely grazing them at any point during the animation is enough to kill you.
It might sound a bit strange, but players are a lot more tolerant of bad collision detection if it’s easier to miss than it should be, rather than if it’s easier to hit. This is even the case when it comes to the player shooting projectiles at enemies. So it pays to be a little forgiving in cases like this.
In the end, you want the player to have fun, and it feels more impactful if an enemy dies from being hit right in the face rather than from a graze, just as it feels more impactful to barely dodge a bullet that looks like it’s grazing you, than it does when that bullet it a few metres off target.
Certainly a good effort for something made in 48 hours though. Game design and programming are both very challenging, so it’s great that you were able to make something like this.
