# Sprite generator
## Install
- Install Python 3.5 or later
- Execute `pip install -r requirements.txt`
## Use
- Using [Piskel](https://www.piskelapp.com/)
- draw the sprites
- export them in `zip` format (it's a .zip containing .png files)
- Place the files inside the [spritesheets](spritesheets) folder
- Execute `python main.py`
- The output is automatically placed in the [output](output) folder

Szia, Ádám!
Boldog karácsonyt kívánok!
Viszont mást is szeretnék mondani.
Most egy kicsit még távolabb fogunk kerülni egymástól.
Persze biztos vagyok benne, hogy ezután is tartani fogjuk a kapcsolatot.
Viszont jó pillanatnak érzem a mostanit arra, hogy köszönetet mondjak.
Köszönöm az együtt töltött időnket.
Köszönöm, hogy más ember lettem melletted.
Ebben neked is részed volt.
Összességében, nélküled kicsit szomorúbb lenne az élet.
Remélem ezt te is tudod magadról.

Szeretném megköszönni azt a számtalan segítséget, amit tőled kaptam.
Köszönöm, hogy mindig támogattál és motiváltál.
Köszönöm, hogy mindig mögöttem álltál.
Nélküled most biztosan nem tartanék itt.
Ha ezt nehezen is fejeztem ki, de mindig fontos voltál nekem.

Viszont mást is szeretnék mondani.
Habár rövidebb, de annál sűrűbb volt az egynyári kalandunk.
Öröm volt téged megismerni.
A kreativitásod és összeszedettséged inspiráló.
