Very cool game, i love it with the item based progression. My first run did a bit well (i think) and i was surprised how many different enemies occur in this game.
My Score:
I forgot to leave my comment here, played it again and have to say:
It's a lot of fun and is also varied due to the machine gun and the Space Invader opponents. It would be cool if the player could maybe use the X key to shoot as well, as some people have a different keyboard layout. But otherwise everything was very good (I don't mention the slide on the paddle, there have been enough others who have noted).
If it was a conscious choice, then all is well. Even found it very useful because I could estimate where I could stay in which shallow water despite the warning, as well as see the effects of an upgrade. To the music. Personally, I think that even if it only lasts 10 seconds, if it fits and is not annoying, then it's actually quite good. I fail at both points, so I use what already exists. The changes in the music are not actively noticeable, but neither do they have to be. ;)
PICO-8 is of course more difficult with less programming experience, but the game is very good for that and maybe you can share it in the Lexaloffle forum for more feedback and players. :)
The game is very cool and has depth with this integrated shop system and the wide sea area. And you met the limitation very well. The music is also pretty well done (especially in the short time with programming and art) and relaxing. One fun thing that I came across by chance is the debug mode when you press Z + X or C + V. I don't know whether on purpose or not, but you could define a boolean variable that you can toggle on and off for the release version that prevents this. :)
So for 7h the game turned out really great. Maybe not based on the sprites and graphics, but on depth, features and opponent variants. Maybe I would increase the game speed and make the tutorial doors and texts more recognizable, but as I said, it's pretty good for 7h. The music also makes it pleasant.
Thank you very much for your feedback! Yes, the balacing has to be adjusted in any case. Unfortunately, I didn't have the time to do this. Was too focused on a lot of less important little things, but unfortunately that's how it is. I was restricted to the colors by the Fantasy Console PICO-8 (limited to 16 colors), but of course there are other ways to adjust this. Thanks for your suggestion and have fun in the jam.
Interesting concept. Had difficulty aiming and guessing how far a shot would go. I was also often hit while charging. Could be because I'm too slow with a touchpad, but I like the idea and the art of the game. The notes on control are very helpful. Personally, however, I would place these a little more prominently or larger. Only read it halfway until I died a couple of times.
