Wow thank you! You don't know how much I appreciate gaming experience feedback as detailed and complete as the one you write. I appreciate it very much.
TUTORIAL. Hehe, yes, I wanted to make it interactive because the game starts off strong... There is information about jumping (and double jumping), I think you skipped it, hehe.
SHIELD. I admit that I tried some of this things. Like puting a duration bar and recharging it after a period of no using the shield. But I still have many programming limitations, even with GDevelop. I've only been learning with that program for just a month and a half. and I'm very very new. Before that, I've only made Bitsy games (extemely simple motor of 1-bit games). I like the idea of implementing the bar on the shield itself and the recharging process by destroying enemies (for example). With more time I`ll explore how to code it.
CREDITS. I'm trying to improve in that sense, it's something we all leave for last... I think, anyway, I forgot to put the author of some assets, I'll have to check it.
SCREEN. Oh! That error you mention has not appeared on any screen I tried. Have you tried playing it on the Gd.games website? Which resolution are using? Maybe I need to check the propeties of the project to adapt the resolution...
Again, thank you very much!!! ^_^
