Thank you so much for your nice and fantastic feedback!!! We thoroughly appreciate your recommendation and wish to hear more from you ABSOLUTELY!
A little about your productive comments: Yes, you are right! However, we should say that the game was designed for mobile platforms such as Android and iOS. We had the leaderboard connected to Google Play and more cool stuff. But, we decided to publish the game here on many platforms to get more users and feedback before we jump into the huge Google ocean.
Also, we were looking for an artist to polish our simple materials but, our budget never let us find a proper person, sadly. Fingers crossed and let's see what would happen in a near future.
Thanks again for your cool comment! It made our day! <3
Filaipus already mentioned most of my issues, as we've talked a bit in a different place, so I am just going to focus on the design aspect. I'd second any of his mentions (especially the text adjustments) and also throw in another mention of playing around with pixel/voxel graphics for the main character and potentially rebranding the game name. Most people looking for this type of game are primed to look for "Runner" names, maybe something like "Void Runner DX" or whatever, just a random idea, but I highly suggest finding a different character style first and then brain storming new brand ideas.
I would also really suggest you work with very simple blown up pixel graphics and try to get a first version up to see how you like those (there are plenty of free pixel/Voxel assets out there)
They might not even need to be fully animated, just a 2 step animation might be enough (think the first bit trip runner or the little character from the game and watch series)
Actually, you might even get away with trying entirely 2d pixel assets as well, as the game is relatively flat anyway. Do play around with those! That would also allow for an endless amount of fun unlockables that could be simple assets.
I was already thinking of offering the Steam release fee as well, but I see filaipus also had that covered ;)
Do keep us in the loop please. I want to see where you guys take it from here and would love to playtest some more when you come up with a new version or you need some opinion on character design decisions.
