So far it has a good atmosphere and the resource management side makes the simple mechanics feel less simple. The stealth still feels a little goofy like in a lot of games where how far you can see is limited and you almost run into a guy but he still doesn't see you, although that seems to become less common as you go so it seems like the stealth becomes less forgiving.
You can one shot enemies and get a few bullets at a time, You run faster but the large amount of enemies means you can't take on a whole camp. Your able to hide again so this means you can ambush one or two guys, grab the loot quickly and then run and hide.
The environment of levels is also good, its simple but it has the needed nature and tents to make it feel real.

I would recommend having a indicator point to the full screen cause I feel like thats important.

Also someone was asking how to get bullets, they randomly show up when looting piles of bags or tents, they can also drop from pigs with knives but thats rare.

Cool idea, Its hard to actually build due to the rounds starting instantly after the last enemy goes down, so I end up just disabling the last enemy so he cant hit me and just put together a fortress and then start the next rounds. I guess its supposed to be difficult to put stuff together but the parts are simple so not a lot of planning is needed.

Doing it the way I did it did make it more boring.

I feel like its cool though and would benefit from being given a larger map. So adding more mobility is more useful and you can hide from enemies to add attachements while still being under threat because the enemies are still approaching.

Its fun to jet back around with a flame thrower and its interesting but since I can't see very far I keep running into things as soon as they enter the screen and you move so fast especially when falling even if your trying to hover with the flame thrower depending on how you fall. I just wish I could see more.

Also the fire effects are awesome. Really like the jet back flame thrower idea.
