Very solid arcade game with some great visuals and sound effects. I have only been designing games for the year and half consistently and in that time the one lesson that has been constantly pounded into my head is that creating interesting choices for the player is what creates engaging games. I feel like this game lives up to that lesson. Throughout this game the player must choose whether to use the ammo on this block or that block even if it means one will disappear, whether or not to shoot that other block or let it fall naturally, and when and where to engage your enemies so that you have the best chance at mobility if things go awry. Overall, I feel like this is a really strong entry from a gameplay perspective.
Now as far as the visuals and audio go, i believe they complement the game well, it was very intelligent for the color motif of all the threats to be green because this is what allowed me to realize the water levels were rising and that the water/acid was dangerous. (I didn't notice at first). The audio was similarly polished and did not get irritating during my playthroughs.
As for feed back, I'm not 100% sure on this so don't go on a wild goose chase if i am wrong but i feel like maybe the heavy explosion block was a bit wonky, I cant quite put my finger on what it was about it, but for some reason it felt underwhelming and unimpactful compared to the rockets. Minor gripe hardly a thing really.
Overall I feel like this game came across as practically a released commercial project, I would not be surprised to see something like this do really well on an app store. Very polished and impressive work from the team.
