I feel like I might be missing part of the gameplay. All I can figure out is to shoot monsters. If there is more I should do, let me know and I'll give it another play!

Notes taken during playing:

oh, got launched right into the action!

I'm a cute little soldier dude, are these crabs attacking me?

music doesn't really seem to fit

the chicken on top of the house is awesome

is this all hand-drawn? It's got a cute vibe to it. Reminds me of old old games, like Turrican

how do i use the CHAINSAW?!

enemies move so fast and then push me, I end up just spamming click versus aiming from a distance

do I have a health bar?

hard to control gun aim

what are these gold stars in the middle? edit: in your screenshot it shows that as a UI bar showing seasons. On my screen it's in the middle of the map beneath rocks.

guessing the purple stuff on the ground are random void zones

can I plant? 

might be missing some of the gameplay here, can't figure out what to do except kill monsters

Our games are pretty similar - both in their idea and their "not quite ready" state ;-)

One can see some hints in which direction you were heading - 5 days is just such a short amount of time, I am sure you worked pretty hard to get to this promising state, maybe you keep it up and try to finish post Jam?

Ah real pity you took on too much and couldn't get there. You really have to go for a solid small feature set and have 'stretch goals' for other things you'd like in a game jam. It's called the MVP, minimum viable product ... what's the absolute minimum featureset you can have and be happy enough.

Of the games i've played so far though it's one of the most unique concepts, no one really did a 'go regenerate the world' kind of theme.
