Freedom Fighter - Rise of humans *WORK IN PROGRESS*

Hahaha, difficulty is hard to assess for the developer

For example, when I did Transball, I really thought the game wasn't that hard. But that's just because I had played soooo many times during development, and I knew every little detail of the game. Difficulty perception for new players is very different

I just want to add my thoughts to some of the points you guys were discussing above:
- I also vote for being able to skip the intro. It only plays once, but for example, I do not have much time to play continuously, so, every time I play one game, I launch the game from scratch. So, that's 1/2 minute every time I play 1 game
- About enemies coming from behind: this is a complex issue! Some games (e.g. Uchusen Gamma) give a warning when enemies come from behind, which is very welcome. Others do not give any warning, and you have to be on the lookout. That works better in horizontal games, as the screen is wider and you have more space. In my game I went for a middle point: no warning, but enemies spawning from the back only spawn from two different points, and always the same two points. So, there are "safe" regions of the back part of the screen. But this is a matter of game design, so, I think it's up to you

I have tried all your suggestions...but no luck...

You can emulate a turboR in openMSX.

The matter is the number of tiles involved. The code load font tiles during i tro, from bank7 of ascii16 mapper. And due to the needing double buffering and the possibility to write on all the screen they've been copied in all of 3 blocks 2 times (every half block is used for double buffer: 0-127 values first buffer and 128-255 second buffer). I can't reload rhe fonts everytime I need them or I had to switch bank, because I need almost the whole room of every bank for each level to store two exchangeable tileset to scroll, different sprites, different music, different pattern different boss (wich tiles has to be doubled too and must fit in the remaining room! Now I'm at work but lately I'll post here screenshots of every tilesets from intro to final level. Font's tiles are always untouched.
And trust me. He did that image only to provoke me. I know him and the fact that he was banned from the most part if FB groups he subscribed is a fact...
Soon I'll talk here about the scrolling technique I used and all will be clear. You just habe to know that first 60 tiles are used from scrolling routine giving 30 dynamic tiles (to have a 1pixel scroll by simply drawing precalc tiles you need 30x8=240 tiles sp it couldn't be possible to have fonts and bosses, nor double buffer too)
