Oh, hello there! I forgot to say but the Green player moves with arrows 😅
Awnsers:
1. I made detailed arts with aseprite, and simple ones with construct, and the cactus support the gameplay making it more strategic, and the grid is to make players fall in "dirty" water.
2. Aseprite and FL studio (1st paid version that I forgot the name).
3. No, it wasn't, but secretly I was helping my brother to beat some cuphead bosses so I didn't have time to make it good enough.
4. Maybe I would make modifiers and map select, with bigger maps and more obstacles.
