I very much liked this game! It's unique, has very nice effects, art, animation, and sound, and it's obvious a lot of great effort was put into it. However, it may be just me, but I felt that this was very challenging and everything was introduced too fast. I understand that difficulty can be a very good thing, but as a completely new player to this sort of genre I was struggling all throughout with very little to try and slowly introduce difficulty and new concepts.
By the second level I was constantly being thrown blinds, erratic drills, and earthquakes, all while I was still learning how to even play the game and trying to comprehend how all of the positive and negative effects boxes work. Some of the level design for the earlier levels could have been a little more merciful if you asked me, on the second level I failed twice when there was only the bottom left purple ore left, which was very frustrating for me. Levels don't move quickly either, they tend to take a little while for the unskilled player
The reason I was failing so hard was unquestionably my skill level, but I felt as if the difficulty curve was very high starting from the second level. Again, this is because I'm terrible at the game, but it should be assumed that most newcomers will be terrible when they first start. I'm not saying water down the entire experience to appeal to a more casual audience, I just feel like the harder levels should be saved for later, and much easier levels introduced at the start to smoothly push the player into skillful play. More experienced players would theoretically be able to breeze through those early levels and get to the more difficult stuff, while newer players would be presented with something equal to their skill level at the start.
Maybe I'm in the minority on the difficulty, and that's perfectly possible and valid, I'm just speaking from my personal experience.
I'm certain this game is probably a blast with some more practice and experience, but in my opinion there could have been a little bit more room at the start to foster that skill, instead of having beginners bash their heads at some really hard levels to start, because I don't find that to be all that fun.
From the other reviews I read I'm probably in the minority about the difficulty like I said before, but overall it seems like there's sooo much content for such a little game. 10 levels which seem to be on the longer side, multiplayer, AND a frickin level creator, all available here on Newgrounds for free. Amazing effort and incredible work, you guys deserve plenty of praise, great job!!!
