Very interesting to see a movement shooter metroidvania! I like the pixel filter, and although the environments feel a little bland, I can't say much, as my 3d modelling skills are non-existent. Just a few things:

- Harvest, at least with the first gun, is literally useless, since the player can move so fast when moving anyway. All of the harvest-gated areas can be skipped with diagonal running (holding W and D or A at the same time), even straight from Grey to Blue without gaining any abilities, although the jump is considerably tighter.

- I struggled initially to tell what was the harvest bar and what was the health bar. Even a small heart image beside the health bar would help to distinguish them, along with a flash on the harvest bar when you hit enemies.

- The snowmen sinking into the ground is just annoying. It can be fixed by just entering and exiting the room, but why?

- LOADING DOESN'T WORK. I mean, I believe it might have worked on my first death, I can't remember exactly, but every other playthrough, I had to quit the game and start all over again, re-entering my settings too. Which lead to me skipping all the way to shotgun as mentioned earlier every playthrough. I once got to Blue's savepoint in just over 30 seconds, but there's plenty of room for optimisation.

- It's really hard to tell what the upgrades in the pause menu are. I never figured it out in the end, except for the blindingly obvious heart.

- It's kinda hard to tell if you take damage unless you're staring at the HP bar. Even a red screen flash would help.

- I can appreciate that it was the last weapon, but the sniper rifle has no harvest special.

- Uh, was there a way to switch weapons? Because if there was, I missed it.

- The game doesn't fit into the theme (except for the name pun).

- Finally, this is completely my fault, but at the ending I softlocked myself because I skipped slide. I couldn't access that cool-sounding playground :-/

This game definitely has a lot of potential! I can't wait to see more of it!

Some of the default settings were interesting lol the filter is super odd and made it a bit straining on the eyes. I finagled with settings in the red area, the minimum X Y were hilariously awful and the max was crack cocaine aiming, but I appreciate the freedom to get it juuust right. 

I like the sound effects and the upgrades were cool! Shotgun blasting your way as a double jump felt great. I wish there was music! Hope you finish this. Definitely a neat concept and it being 3d is a plus for me. Hop you end up playing ours!

In general, the game turned out to be interesting. I liked the mechanics, according to which each weapon has its own abilities. Of the minuses - the red location slightly strains the eyes
