Saw this game on Twitter today and like it a lot. There's a major problem for me with the campaign though: I can't get past the first level. I can make it to around $2500, but I always run out of energy despite my best efforts. I think this game has a lot of potential, but I found myself playing the initial level roughly 20 times, and as a reward, was only able to afford a lab upgrade that i didn't really understand (i bought it anyway). I also got mutations too, though I'm not entirely sure how that system works.
I have a few friendly suggestions I thought you might be interested in: Since the movement is super difficult, the initial stage would have been much more satisfying with slower/ smaller targets to crush. After that, you get some cheap beginner upgrades and move on to the next stage. As it is, I just don't feel I have the technique or buffs to get through the big buildings and fast moving cars that early on. Making danger more visually obvious would be welcome too (to me, sign posts don't read as dangerous to a massive nuclear monster, but more as an easy destructible target). I also think that since energy is such an issue, health, powerups or straight up money crates in the stage would be great. These would also provide mini objectives to aim your destructive path towards. The look, sound and feel of this game is executed perfectly. I think my concerns are just about making the upgrades and leveling-up more gentle, smooth and understandable. Oh and one last thing, I found the game to be pretty blurry on highest settings. I think this was due to an intentional image effect, but I was squinting at a few of the UI tutorial texts. Anyway, great job, I look forward to playing more and thanks for reading my rant.
