Funny enough those waves aren't even waves every second  enemy spawns and rushes at you. and to be honest i's kinda child of my improvisation after failed attempt to implement  a* alghorytm (i planed to populate whole map with forest and you cloud build house anywhere and enemies atack you )  so instead of populating whole map with tress it's 24X24 tiles of grass with point in centre where you're teleported during a night and blocked.

But i'm already trying  to "undo" some changes and  already i unlocked moment during combat (to witch you can switch by key not automaticity triggered by night). But enemies still go in straight line at you and thus block at objects.

If i will go further it probably gonna be different,probably different feel and spirit that this prototype here , but i want to make combination of resource gathering and combat when you actually have to fight for your freaking live. Time will tell if i will find enough discipline in myself to make something out of it.

Funny enough those suppose to be allies but i couldn't figure out design with i would draw efficiently.

PS. To be clear you can be in fighting mode just 20 seconds after with you can start building but after 20 sec. passes building mode will trigger only if there is no alliens on the map (including those beyond FOV)... yea even with limited time i think i could do it better but well. Mistakes were made.

Yea i'm aware of problems with bullet collision detection, sadly i couldn't figure  it out(especially that on Desktop version it worked fine) in time and only one of the commenters give me trope that it might be problem with frame rate.

In case of refreshing issue well i kinda forgot to add some reset of the game and at the end of jam i decided to just add information to refresh to end game.  Maybe at least i learned something.
