Clickteam Fusion 2.5
Push through one baffling hour with the event grid and you can ship a small 2D game in a weekend. Push a big project through it and you will feel every seam.
GamerScout Verdict
Best for non-coders who want one small 2D game finished this month, not a flexible engine to grow into.
Compare Prices(2 stores)
Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.
Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.
We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.

About Clickteam Fusion 2.5
My first hour with Fusion 2.5 was spent mostly staring at a spreadsheet, wondering which part of it was supposed to be the game. The Event Editor is a grid: conditions run down the left as rows, every object in your level gets its own column, and you build logic by clicking cells until checkmarks and crosses land where you want behavior to happen. Nothing about that looks like programming, which is exactly why it throws people. I kept reaching for a script window that does not exist. Then somewhere in the second evening the grid stopped being a puzzle and became the fastest way I have ever expressed the idea that when this touches that, this other thing should happen. That flip is the entire pitch. Survive the hour where it feels alien and you get years of it feeling obvious. What you actually do here is assemble. The Frame Editor is a blank play area you drag Active objects onto, and each one can take a built-in movement (Eight Direction, Platform, Bouncing Ball, a path you draw by hand) with no logic behind it at all. Add a couple of counters for health and score, a collision condition or two, some alterable values to track per-object state, and you have something playable in about twenty minutes. Fusion is at its best inside that window. Prototyping in it feels closer to sketching than to engineering, and the run-frame button is near instant, so the loop between an idea and the realization that the idea is not fun stays very tight. For a certain kind of designer, that speed is worth more than any amount of architectural elegance. The people who get the most out of this are non-coders with a clear, small idea. Artists who want their sprites moving today. Jam entrants with 48 hours on the clock. Teachers running a class that needs visible results before the room checks out. Hobbyists building fan games, arcade throwbacks, point-and-click horror, single-screen puzzlers. The track record backs it up, too: Five Nights at Freddy's and Freedom Planet both came out of Clickteam tools, which should settle any argument about whether no-code caps your ceiling. The extension ecosystem stretches things further, with community-built objects covering everything from dialogue handling to networking, and the built-in sprite and animation editor means you can draw a walk cycle without leaving the program. The trouble starts when the project gets big. Event lists grow past a few hundred rows and the grid that made everything readable turns into a scroll bar with your whole game hidden inside it. Groups, comments and folders help, but none of them substitute for searchable text, and that absence bites elsewhere too. Project files are binary, so real version control is effectively off the table and collaborating means passing files back and forth and hoping. The debugger will happily show you values but will not walk you through logic the way you want it to at 2am. Extension quality varies wildly and leaning on an unmaintained one can strand you months in. Publishing beyond Windows relies on separate add-on runtimes rather than anything bundled by default, and each target comes with quirks you get to rediscover personally. The long, quiet wait for a successor has left this feeling like a tool in maintenance rather than one being actively pushed forward, and performance that holds up fine for modest 2D scenes gets wobbly once hundreds of active objects are on screen. So take it for what it is: an excellent machine for finishing small things and a frustrating one for growing large things. If your plan is a tight 2D game you can describe in a single sentence, Fusion will get you there faster than almost anything else on the shelf, and the 88 percent approval across two thousand-plus Steam reviews mostly comes from people who did exactly that. If your plan is a sprawling multi-year project with collaborators attached, go look at engines with text-based code and real merge support before you commit your weekends. Work out which of those two you are, and the decision here makes itself.
