I have a few changes that I think would be healthy for the alien class that could be added in the next QOL update.

1. I think that the aliens for the alien class could be revived using bandages. This would be cool because they are a big part of the alien class, but they often die in the first town or you end up saving them for a very long time, just to use them as meat shields/distractions. While you deal the real damage to enemies.

2. The rayfun for the class is not bad, just as he ammo is horrendously low. My suggestion is: you only get one stone which gives 100 ammo and dosent despawn when used. Instaid, it slowly loses its glow eventually becoming a dark green rock as you use it (it has 3uses)The way to recharge the stone would be by having it touch dead enemies. When you use the stone to touch a dead enemy, it would consume that enemy and gain a small amount of its glow back. After consuming 60-80 enemies, it would gain all three charges back. And for every 40-65 enemies you use consume with it, it gains extra charges, stacking up to 5.

3. No great class is truly great without a passive, so it be alien class should take 10% less dammage and have 10% more speed, and deal 7.5% more dammage. In excange the class gains 7.5% less when picking up money, and deives the train 2.5% slower for every team member besides itself currently alive or in the server, and drives the train 1.5% faster for every teamate who is either dead or was here when you started but left.

Ideas for the next QOL update.
In the next QOL update, the class menu would be similar to the trains menu. (In excange for longer, more detailed descriptions of classes + unlocked lore about that class). Lastly, depending on what modes you completed with that class, how many bonds you obtsined with that class, your fastest time,money spent, you would gain exclusive cosmetics for that class (ex: beating nightmare mode with high roller would make the hat red, beating nightmare mode with over 5,000 money spent would make the hat red and shiny etc. also, for classes like the ghost and horse or any class with little visual cosmetics, the title above your head that shows what class you have selected would get cool cosmetic changes)

Thanks a lot for reading my suggestion!
