Hey Artok, thanks for playing! This is some great feedback and we'll definitely take it on board.
The full screen was a little fiddly - apologies for that. If you zoom out a little, you should be able to see the 'blue' full screen button at the bottom which will allow the unity game itself to go full screen and that should solve the issue.
In respect of the hacking minigame, we've had a lot of feedback about how people found this confusing - backspacing should be working as intended, I'm not sure why you were having troubles with that and we'll definitely look into it as we further develop the game. We included a setting in the settings menu for 'E.Z Hack' to help give people a little more time to complete the hacks - both for those people learning the ropes, and to improve accessibility.
In respect of the battles - I fully agree that this is still very rough around the edges. Some of the enemy AI can be very stubborn and difficult to take down by combining turtling and using their heals - especially Akuma Nik for some reason. We plan to add more sophisticated AI behaviours, as well as a lot more combat actions for the player to pick from so that they can overcome different enemy behaviours, though I hope that you can see the potential in the system!
In respect of the CRT effect - Absolutely valid point. We did a lot of work to boost the readability of the text - changing the font, increasing the size and the spacing. But I definitely don't think that we nailed it in this prototype and we'll be working to make sure that it provides that retro experience, but without compromising the readability. And it's a really great idea to include an option to disable that effect! Something we'll definitely look to include in the future.
Once again, thank you so much for playing our game, and for providing this great feedback. I hope that you can see the potential of the game, and will try it out again once we've further developed it! <3
