Blocks Shooter 3D! Run, Shoot, Merge Weapons!

So you pick a level, and you're dropped onto a straight-ish track that's got enemies, pickups, and obstacles scattered along it. The core loop is simple: you run forward automatically, and you swipe left or right to dodge stuff or line up shots. Your character has a weapon that starts pretty weak -- think peashooter. But scattered on the track are weapon parts, little glowing cubes that you run over. Collect enough, and your gun levels up mid-run, getting bigger, faster, or adding extra barrels. That's the merge mechanic -- it's not like you're dragging pieces around; you just hoover them up, and at certain thresholds the weapon transforms. The first upgrade turns your single-shot into a two-shot burst, which feels good against the early stickmen who die in one hit. The satisfying moment comes around level 3 or 4 when you've merged enough to get a spread shot or a laser -- suddenly you're mowing down rows of enemies instead of picking them off one by one. The enemies themselves are basic at first, just stickmen that walk toward you. But later levels introduce shielded guys that take two hits, then fast runners that zigzag, then big chunky ones that block the track. There's also traps -- spikes that pop up from the floor, rotating bars you have to swipe under, and gaps in the path. The difficulty ramps up because enemies get more varied and more numerous, not just tougher. Around world 5, you'll see flying enemies that hover off the ground, requiring you to time your shots differently. The workshop between rounds is where you spend coins you've collected on permanent upgrades -- faster reload, more damage, wider shot spread, that sort of thing. It's a separate screen where you tap to buy upgrades, and each upgrade has multiple levels. The game doesn't explain which upgrades are best, so you kinda figure out that investing in shot speed early helps more than raw damage. Controls are just left/right swipes, but there's nuance -- you can swipe quickly to dodge, or hold a direction to drift toward a particular pickup. Your brain is constantly scanning: what's coming up, do I need to dodge or can I grab that weapon part, is there a shield enemy I need to save my charged shot for. The run lasts maybe two to three minutes, so it's snack-sized sessions. There's a boss fight at the end of each world -- a giant stickman that takes way more hits and has its own attack patterns. Beating it feels earned because you've been upgrading both during the run and in the workshop. The game doesn't have a story, really -- it's just about surviving and stacking power. The visual style is blocky and bright, very Roblox-inspired, with a third-person camera behind your character. It runs in browser, no download needed. Load times are quick. One thing that's annoying: sometimes the swipes don't register if you're too fast, so you'll run into a trap you clearly avoided on screen. But most runs feel fair. The weapon merging is the hook -- seeing your gun evolve from a basic block to a multi-barrel monster is what keeps you starting another run.
