Hi ! So I've tested a bit the game, it crashed as soon as I arrived to a first mini boss (I've played with a controller and tried to attack with one of the alternative missiles).
Apart from it, I feel like the overall UI could be improved. For example, when in the shop to buy missiles, you could highlight which items are being bought. A clearer description of what does each item do could be interesting (I'm a beginner in shootemup in general).
In my experience for this demo, I felt like the dash wasn't that interesting compared to the shield. When looking to your trailer, I feel like this is the most interesting choice to be protected against ennemies.
I might try again the demo someday, I feel like I wasn't the target audience but it was worth a try :)
