The game has a very interesting idea. However, let's be honest, you won't be able to make a big game out of it without developing the mechanics. Although what is shown in the game is quite interesting. They will tighten the graphics, game design, and sound design, and it will be interesting.
?? I thought all that was showcased would be great as is! Though, as with any game, adding more levels/characters/etc. would make it more fun to play for extended periods of time or over multiple sessions because there would be more to do.
As for, "They will tighten the graphics, game design, and sound design, and it will be interesting," I imagine your comment wasn't meant to come across as such, but this part sounds especially condescending since... well... the game is alreadyinteresting-- you said so yourself! Plus, all three of those aspects you mentioned are quite polished in-game. Like... d'you see those vines?? Dayumn! And don't even get me started on that crunchy ground texture-- mmmm!~
Overall, I'd say this game is one I'd love to come back to play again and again in the future!
I probably did not formulate correctly (And perhaps the translator is stupid, lol), I did not mean that the game is bad. I really like the idea itself. The game and the idea is great, but it is unfinished. Once again, I'm not saying that the game is bad, I want to say that it needs to be improved!!!
