I have played your game, and I have to say that it gave me a throwback to the good old "Paratrooper" and "Ganja Farmer" days :) I played that and similar games quite a bit!
I found a DOSBOX version of the original Paratroper game here: https://www.retrogames.cz/play_616-DOS.php
See my playthrough here
The game as such is a really good start, and the general gameplay loops of the game is solid and are working. Where you could put a bit of work would be on the balancing side. Maybe descope it a bit, and only have 1 difficulty mode, and really work on getting that in a perfect shape.
What I liked about the game:
- The core and supporting loops where really nice, and have what it takes.
- The combination of moving and shooting I have not tried in this genre of games, and I liked it.
- The reference to space invaders was cool
What I would improve:
- There was a few obvious bugs that should be fixed (Upgrade menu and scale)
- A intro tutorial is needed, it took me a long time to realize that I could roll with the cabbage.
- I would put a direct link to the "upgrade" shop in the game over screen, instead of only play again and main menu.
- The balance was somewhat off, it felt to difficult and chaotic to begin with, I would really try to make a slow progressing here.
- Add some aircontrol of the cabbage, it was super frustrating to be unable to control the cabbage while in the air.
Thank you again for testing my game: https://itch.io/t/3658231/strategy-game-about-bunnies-building-a-rocket-gameplay...
