Thank you so much for your review!
Most oft the things you have listed here as negatives won't be a factor anymore when I update the game after the jam is over. But I also understand that you have to rate the game as it currently is. During development I focused more on getting my code base right, so I can easily expand the game later on (for example, I already have double the amount of upgrades in the game, just deactivated most due to time constrains). The upgrade system is something players will have to explore for themselves over multiple playthroughs. The same goes for the game world and all its hidden secrets. But that's why I have the narrator(s) and the dialogue talk about the upgrades and what their purpose is. The whole tutorial section isn't really done yet, like as you mentioned, there will be introductories to single enemys and the combat system and all that. It's all planned out, one week just hasn't been long enough doing this all by myself. The game will eventually have a save/resume anywhere playstyle for the story and a dedicated speedrun mode with virtually no downtime and disabled dialogue. And SO much more! If you liked the whole idea of the game (which it seems you did), please try out the game again after its first official update (after the voting phase is done) and see, if it changes your mind. Thanks again, Sfunk!
