Hello, I would like to suggest some improvements that I think are useful.

When I play in endless mode, around 1 hour of play on the same map, I notice a fairly significant drop in fps, even though I still have a ryzen 7 and an rtx4080, for such a small game, it seems surprising to me. And it continues until the game crashes outright, making us lose all the time spent on our game.

What I would like to suggest to relieve the graphics engine a little, first would be to be able to make the effects of weapons more or less transparent (from 100% to 0%), because some weapons like the magnetic cannon and the very last one whose name I forgot are ultra painful to see, it's pretty I'm not saying the opposite, but after ten minutes it's painful.

Then, all the experience cubes on the ground, either you could make them agglomerate with each other after a certain number of seconds, so we would go from 2000 white cubes to 30 pink-orange-red-purple cubes...etc. I imagine that with so many fewer artifacts, it will relieve the graphics engine. After I understand that for the buff that we get with the experience skill for each time we loot a cube no longer works correctly. So, instead of making them agglomerate, you could simply increase the base loot distance. So, when we improve the entire exp skill tree, it would allow us to loot all the experience even off-screen, so no more stuff lying around on the ground, less load on your graphics engine.

Otherwise, when playing in endless, the monotomy after the first 10 minutes is heavy, I'm not even talking about exceeding an hour of play. What would be nice, for example every ten or fifteen minutes, would be to see our mecha take off to go to a new biome, randomly. Firstly it would be pretty cool to see, secondly it would change the biome and wake us up a bit.

With regard to the crash I was talking about at the beginning, a way to not completely lose progress, even when the game crashes, would simply be that when you kill enemies in the game, rather than seeing a death counter that is totally useless as possible, all the enemies killed IMMEDIATELY give the game's currency. So, even after a crash, when you restart you would just have lost progress on the map, but not the hard-earned currency. I'm not in the case where it would be of much use to me anymore, since an endless of one hour makes me win about 450k and I don't even know what to do with it anymore, it's a bit of a shame at this level, but for those who start the game, if they have small configurations and have crashes, it could prevent them from raging heavily ;)

In any case the game is nice and I'm curious to see the next updates ;)
