This game is my submission for the LOWREZJAM 2022, which requires games to have resolution of 64x64px.

Enemies are approaching. There are 10 waves of them. We need to survive.
There are 3 types of towers you can build:

laser - the fast one,
v-beam - the stronger one; its beam covers all tiles above and below, therefore you cannot build anything else on its way,
booster - this one makes all surrounding lasers and v-beams shoot longer and re-charger faster; you can 'stack' boosters to increase total boost - each laser can be boosted up to 8 times and each v-beam up to 6 times (not 8, because 2 tiles are reserved.

Our base have 5 cores. Each enemy is capable of destroying one core. Without cores, we cannot survive, it's that simple.
Good luck! You are our last hope…
