It's fine. The gameplay is really fun in the beginning. The jump is floaty, but still offers a high amount of precision. This gives the jump and dodge gameplay a really fast paced and fun feel. Unfortunately, the game introduces a weapon power-up which works extremely slowly, and thus incentivizes a much slower form of play, despite that not being the most enjoyable experience.
Despite what flaws I've listed, my review would be a fair bit higher if the game didn't overstay its welcome. The last chunk of the game gives you a power-up that makes mobility a lot easier, without necessarily making it more fun, and then forces you to go from one corner of the map to the other and back again. It really turned the whole last fifth of the game or so into an anti-climax.
