Towers of Survival

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


  • in-game button X or keyboard key X or V - enter tower building / choose a selected tower / place a tower
  • in-game button O or keyboard key Z or C - open menu / cancel
  • in-game arrows or keyboard arrows - select next or previous tower / choose a place for a tower


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…


It's a PICO-8 game, therefore I had to sacrifice some clean code practices in meeting console's constraints. Currently stats looks like:

  • the codebase uses 8136 tokens out of 8192 available (29 left, 99% used),
  • the codebase consists of 64084 chars out of 65535 available (1451 left, 98% used).
